SonarQube, no data for depth inheritance tree and other metrics - configuration

Hi this is my first post on legendary Stackoverflow!
I am currently trying to find a platform in order to create an inheritance plugin (in order to calculate metrics) for my thesis and I am trying SonarQube for this purpose. So far, I am learning the basics. The problem is that although everything goes fine, I have a problem when it's time to add a "custom measures" widget. As you can see, the widget shows the message "no data" on configure widget menu, when I add measures like Number of Children, Depth in Tree.
I have installed SonarQube 3.7 for Windows 7 64bit and SonarQube Runner version 2.3. I have also installed SonarQube on eclipse. My .properties file is this :
Thanks in advance :-)

The computing of LCOM4 and RFC metrics is based on byte-code, so if you want to have them, you need to:
compile your code
add the "sonar.binaries" property in your file (it should point to the folder where the code was compiled, e.g. "target/classes" or "bin")
As for the 2 other metrics, they are not fed by SonarQube. So we'll eventually remove them (https://jira.codehaus.org/browse/SONAR-4643).

What are the output files of the VxWorks Workbench kernel configuration GUI

I'm trying to generate a VxWorks 6.9.4.8 kernel configuration that is identical to another kernel workbench project. The Workbench 3.3.6 only allows GUI configuration.
Is there an underlying kernel configuration file, produced by the GUI, which can be replaced?
After updating the kernel configuration using the Workbench GUI, I see the following files have changed:
linkSyms.c,
prjComps.h,
prjConfig.c, and
prjParams.h
I guess my question is, which one, if any uniquely identifies the kernel as built?
prjComps.h will contain all the component's names, as you have chosen in your kernel configuration GUI.
First step to create new Kernel configuration based on some other Kernel configuration is to use GUI configurator and add the missing component in prjComps.h, Better use some diff tool like 'beyond compare', and keep reducing the differences by adding/removing the components. Remember not to edit this file directly, but via GUI configurator only. As the tool calculates the dependent component and adds/removes them.
Second step is to create the new prjParams.h as above.
The Workbench actually allows to use command line to edit Kernel configuration via vxprj tool in vxworks 6.9(this tool has been replaced by "wrtool" in vxworks 7), you can right click on the Image project and chose 'Open Wind River vxWorks 6.9 Developement Shell'.
If you want to add a component for e.g. telnet client (INCLUDE_TELNET_CLIENT)
, you can use the following command
vxprj component add INCLUDE_TELNET_CLIENT
To remove a component
vxprj component remove INCLUDE_TELNET_CLIENT
For more of vxprj tool, you can look up the documentation in the workbench itself.
The project configuration is held in a handful of files in the kernel project directory.
These are:
.project
.cproject
.wrproject
projectname.wpj
Files such as prjComps.h, prjParams.h prjConfig.c are all generated by the configuration tool, however these are not configuration files themselves. Instead, this is generated C code that contains, amongst other things, a list of selected components.
These files are also re-generated, I believe, when you rebuild the project.
As such, these are not really the authoritative source you are interested in.
For this, you need to look at the project files. In terms of a list of components, the most interesting is the .wpj file, which contains amongst other things a list of explicitly and implicitly included components.
The explicitly included components are those you manually selected in the Kernel Configuration GUI, the implicitly included are those that were then included to satisfy dependencies.
This distinction can sometimes make comparing kernel configurations tricky, then you may want to fall back on the generated files eg prjComps.h, however you should always remember that this is a representation of the configuration, not the source.
The .project etc configuration files are big and complex, but a decent diff tool, such as BeyondCompare can make comparisons of the project directories fairly easy
Thanks for the clue, #endTunnel. I looked at that file, and noticed that a few files get modified when I save my GUI selections.
prjComps.h - all the components #included in the kernel build
prjParams.h - the additional parameters set for the enabled components
prjConfig.c - the configuration and initialization calls for each module included.
'linkSyms.c' also gets modified. Not sure how that is used, yet.
I can now use diff to compare kernel configurations, and perhaps even duplicate a configuration (haven't tried that yet).

Customisation of Jtest in Eclipse

I am new to parasoft J-test, I want to customize the static analysis of J test in eclipse. I am able to customize what all the rules I need to check in static analysis but I need to change the severity of the rule. How can we change the severity of the rule?
I am using parasoft J-test 9.5 version which has eclipse.
Excellent question. In your Jtest 9.5 Eclipse IDE, go to the Help menu and select Help Contents. In the documentation tree on the left, go to:
Parasoft Jtest User's Guide > Static Code Analysis > Modifying Rule Categories, IDs, Names, and Severity Levels.
Parasoft's documentation is comprehensive and easy to follow. Plus, it's very easy to search because it is built into Eclipse.
If you have any questions that are not clear from the documentation, or if you have ideas for new features, Parasoft's Support Team is very helpful and normally responds within a few minutes. You can contact them by going to www.parasoft.com and selecting the "Support" link at the top of the page.
Full disclosure: I am a Parasoft employee.

Can't get MVVMCross core project to reference System.Xml.Linq

I'm quite new to MVVMCross but I've been actively using it for two weeks, at work and in a school project, and I am really enjoying it! Unfortunately, I've been stuck on the school project for 2 days now : we're asked to do a mobile Jabber client. This is not a big deal since I started it using Matrix XMPP library, which does most of the job and is easy to use. I decided to restart my project using MVVMCross, in order to have cleaner separated code and add a Windows Phone project, but Matrix absolutely needs System.Xml.Linq, and I can't get the core PCL to compile :
The type 'System.Xml.Linq.XElement' is defined in an assembly that is not referenced.
You must add a reference to assembly 'System.Xml.Linq, Version=2.0.5.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'
As shown in Stuart Lodge's tutorial videos, I'm using profile 104, the the faulting dll is really present in the folder, I can't add it manually to project's references since VS prevents me from doing it (gently explaining that it's automatically loaded since .Net portable subset is included in references), I've updated and repaired my VS install "just in case"... and have no more idea left.
So, here are the questions :
is it really possible to use System.Xml.Linq with MVVMCross? or did I miss the big title explaining that what I'm trying to do is stupid?
if yes (that'd be great!) did/does someone experience the same problem? Even more interesting : did someone find a solution?
Thanks in advance!
Additional info : Windows8(x64), VS2012 Ultimate, trial license (school project...) for Xamarin.Android
UPDATE : following Stuart's answer, I compiled and ran the BestSellers sample, which uses System.Xml.Linq... without any problem. As it comes with an explicit reference to System.Xml.Linq (see first link in answer), I tried :
to delete it (and a few others) : VS holds it's promises, and really includes needed references as long as .Net Portable Subset is referenced, so everything rolls smooth.
to manually add this reference via Notepad to my .csproj : it doesn't change anything.
One thing tickles me in Stuart's answer : "perhaps it is something to do with the way the matrix uses XML.linq". Since the Matrix type I'm trying to use is just a descendant of System.Xml.Linq.XElement, which is widely used in BookViewModel.cs from sample, what could possibly be wrong with that?
"Solution" : The problem seems to be due to Matrix requiring a special version of System.Xml.Linq, which is not the one included when profile 104 for building PCL. I used file linking method as a workaround to share the core, and that works, though this is less elegant, readable, and harder to maintain...
Yes it is possible to use at least some of System.Xml.Linq
For example, see the BestSellers sample
csproj file - https://github.com/slodge/MvvmCross-Tutorials/blob/master/Sample%20-%20BestSellers/BestSellers/BestSellers/BestSellers.csproj#L49
example XML linq use - https://github.com/slodge/MvvmCross-Tutorials/blob/master/Sample%20-%20BestSellers/BestSellers/BestSellers/ViewModels/BookViewModel.cs#L44
For the problem you are seeing, I'm really not sure what the error is - perhaps it is something to do with the way the matrix uses XML.linq? You might have more luck of you open up this question to other tags like portable-class-library, XML-linq and windows-phone.

Xtext project creation concerns

Before I begin I must admit that I am new to Xtext and the designing of DSLs. Some of my questions on this matter may be somewhat "less than intelligent".
I have created an Xtext project using the IDE, and I am simultaneously using one of the sample projects provided with Xtext as a guide to what I need to do in my language. I am seeing a lot of warnings that are making me nervous.
Apparently, when the development environment creates a new project, it somehow configures that project to use the Java 5 libraries. I am using Java 6, and as a result I get warnings saying that my project is configured for Java 5 and there is no Java 5 on my system (which there isn't!).
I have tried altering the build path so that it uses Java 6 libraries, but this generates a number of other warnings -- including warnings that the Java 6referenced in my manifest.mf file is invalid!
Then there are the "plugin.xml" warnings. Apparently, the build.properties file references a file called "plugin.xml" which is not created when the IDE creates the project. I have no idea whether or not this file is important enough to create, and I have no idea what should go into it.
Frankly, I hate warnings. Warnings tend to lead to future problems in what I produce. I like clean compiles and clean deployments. I would like to eliminate these warnings, before they start screwing me up down the road (like putting in Java6 classes that would break in a Java5 library).
Has anyone been able to eliminate these warnings reliably? Please advise.
For the JDK warning, you simply switch in the Manifest.MF to a target environment matching your preferred JDK ('JavaSE-1.6 ' in your case).
The warning regarding the missing plugin.xml will be gone as soon as you have run the grammar generator the first time, as it will produce such a file.

Missing Linq namespaces (Linq to sql, compact framework)

I spent this morning in trying to figure out where the system.linq.expressions namespace is. The following is what I did:
In VS 2008, Create a new C#/Smart Device/Windows Mobile 6 Professional SDK/.NET CF v3.5/Class Library
Used SqlMetal (in Program Files/Microsoft SDKs/Windows/v6.0A/Bin) to generate the data context.
Added the data context .cs file into the project.
Compile and many errors for missing namespaces: System.Data.Linq, System.Data.Linq.Mapping, System.Linq.Expressions
After some research added System.Data.Linq.dll in c:\Program Files\Reference Assemblies\Microsoft\Framework\v3.5 (The dll was not directly listed when I choose to add reference and I used "browse" tab to finally located the one, which is for normal framework)
Compile again, less errors, but still System.Linq.Expressions namespace is missing.
The document says System.Linq.Expressions is in System.Core.dll but it seems my System.Core.dll (located in Program Files\Microsoft.NET\SDK\CompactFramework\v3.5\WindowsCE) contains much less namespace than document says.
Thanks in advance!
The Compact Framework does not support LINQ to SQL. All objects in the documentation for System.Data.Linq confirms this by being completely devoid of the "supported in the CF" icon. For example, look over at the docs for DataTable, which is supported. You'll see a little icon by each supported method/property.
You cannot "add" support by simply referencing a desktop assembly like you did in your step 5. The CF cannot consume full framework assemblies, for a variety of reasons.
Dynamic code generation (Reflection.Emit) is not available in NETCF. What this means is that a lot of features that depend on this is not available, this includes DLR (dyanmic language runtime and hence languages like IronRuby), Linq-to-SQL/
If you just want the Linq.Expressions and you are doing your own stuff with it i.e. not trying to get linq to sql working then you can use the System.Linq.Expression stuff from the db4o guys.
I am using it on my project using linq to objects.
