I would like to know how I can get the build number into a .txt file in Hudson
Under execute shell
echo $BUILD_NUMBER >> bldnum.txt
Is this right way?
If you're on some version of Linux. On Windows, you'd want an Execute Batch task with
echo %BUILD_NUMBER% > bldnum.txt
(I'm assuming you don't want to append... Builds should be clear of dependencies on previous builds anyways)

I'm trying to install modules from SourceForge and I'm getting an error that a variable named TCL_LIB_SPEC is not set. What is this supposed to be set to?
The answer here is to install the TCL development package
% yum install tcl-devel
This gives you a tclConfig.sh file at /usr/lib64/tcl8.5
So
% cd /usr/lib64/tcl8.5
% . ./tclConfig.sh
Then configure works.
It's supposed to be set to the instructions to use with your compiler for linking against the Tcl C library, and it should (conventionally) be generated by running the relevant configure script inside a Tcl source distribution. Or a distribution of Tcl (e.g., on Linux perhaps called tcl-dev) may have alternate correct values already set up.
I am starting a ruby command from a batch file using STAF.
STAF $TESTMACHINE process start command ruby "C:\MyProject\scripts\MasterScript.rb" WAIT SAMECONSOLE RETURNSTDERR RETURNSTDOUT WORKDIR "C:\MyProject\scripts"
This batch file is triggered by a Hudson job. But my observation is that the print/puts of the ruby files appear in the hudson console only after the completion of the execution of the ruby script [Hudson job]. This way I can not make out if something is going wrong in the script execution unless the job completes.
Also, I understand that if I remove RETURNSTDERR RETURNSTDOUT, the ruby script's output is displayed in the STAF console on the target machine. So STAF is the one which is sending back the ruby outputs to the hudson console.
Now can I use any option with STAF to get the ruby output spontaneously to the hudson console?
Thanks for reading this lengthy question :)
You can use SSH instead of STAF for such task.
It seems with STAF it's a little bit tricky and could be done with OUTPUT option.
If you have shared storage, for example NFS share called /nfs on hudson server and d:\nfs on Windows, the following hudson job should work:
STAF $TESTMACHINE process start command ruby "C:\MyProject\scripts\MasterScript.rb" WAIT SAMECONSOLE RETURNSTDERR RETURNSTDOUT WORKDIR "C:\MyProject\scripts" OUTPUT "d:\nfs\hudson.log" &
tail --pid=$! -f /nfs/hudson.log
I am setting up Jenkins to replace our current TeamCity CI build.
I have created a free-style software project so that I can execute a shell script.
The Shell script runs the mvn command.
But the build fails complaining that the 'mvn' command cannot be found.
I have figured that this is because Jenkins is running the build in a different shell, which does not have Maven on it's path.
My question is; how do I add the path so 'mvn' is found in my Shell script? I've looked around but can't spot where the right place might be.
Thanks for your time.
I solved this by exporting and setting the Path in the Jenkins Job configuration where you can enter shell commands. So I set the environments variable before I execute my Shell script, works a treat.
Some possible solutions:
You can call maven with an absolute path
You configure a global environment variable in the jenkins system settings with the absolute path to your maven instance, and use this in your script call (if you use the inline shell script, I don't know if those are substituted to a called script, you have to test)
You use a maven project and configure your maven instance in the jenkins system settings
ps.: Usually /bin/sh is chosen from Jenkins, if you want to switch to eg. bash, you can configure this in the jenkins system settings, in case you want to configure global environment variables.
You can use envInject plugin. It's very powerful.
I use it to install rbenv. And it can inject environment variables into your current job.
Another option to Dags suggestion is that if you're only using a single version of maven, on each slave server you could do either;
* add PATH=${PATH}:
* symlink mvn into /usr/bin with; sudo ln -s /usr/bin
I'm not at a Jenkins box at the moment, but I can find some more detailed examples if you'd like.
Jenkins is using sh by default and not bash.
This is my first time defining a jenkins maven job, and I also followed soem regular maven instructions (for running from command line...), and tried to update ~/.bashrc with M2_HOME, M2, PATH, but it didn't work because jenkins used sh and not bash. Then I found out that there is a simpler and better way built into jenkins.
After installing maven, I was supposed to configure my maven installation in jenkins.
To configure your maven installation in Jenkins:
login to jenkins web console
click Manage Jenkins --> Configure System
Under Maven, click the "Maven Installations..." button
a. Give it some name
b. and under MVN_HOME set the path to where you installed maven, for example "/usr/local/apache-maven/apache-maven-3.0.5"
Click Save button
Define a job with maven target
edit your job
Click "Add build step"
on Maven Version, enter the name you gave your maven installation (step #4 above)
set some goal like clean install
I've made a NSIS script to create an installer for a Rails application.
The application uses JRuby and Java.
In the first section of the installer I set the environment variables: I add jruby\bin to PATH and I create JAVA_HOME variable, which points to Java\jre6.
!define JRubyBinPath "$PROGRAMFILES\${PRODUCT_PUBLISHER}\JRuby\jruby-1.6.3\bin"
Function SetEnvVars
# set JAVA_HOME
${EnvVarUpdate} $0 "JAVA_HOME" "A" "HKCU" "C:\Program Files\Java\jre6"
# add jruby to Path
${EnvVarUpdate} $0 "Path" "A" "HKLM" "${JRubyBinPath}"
FunctionEnd
Section "Pre" SEC01
Call SetEnvVars
...
SectionEnd
** All the paths are correct. **
In the second section of the installer, after packing all the application files and JRuby files, I initialize the database using the following commands:
Section "Installer" SEC02
...
SetOutPath $INSTDIR
nsExec::ExecToLog "jruby -S bundle exec rake db:create RAILS_ENV=production"
nsExec::ExecToLog "jruby -S bundle exec rake db:migrate RAILS_ENV=production"
nsExec::ExecToLog "jruby -S bundle exec rake db:seed RAILS_ENV=production"
...
SectionEnd
The problem is that when I run the installer on a clean Windows system, all the code executes correctly, except for the lines that contain commands using "jruby". I get no error in the installer window, it just won't execute those lines.
Anyway, if I manually run those commands in a console right after the installer finishes, everything works as expected.
From what I have seen so far, the problem is that the installer cannot access the environment variables until it finishes.
* What I have done so far to solve this problem is creating the main installer Installer.exe (here I pack all the files and I set the environment variables), and another executable Init.exe which initializes the database.
If I manually run these executables - first Installer.exe then Init.exe - the application installs correctly. But if I try to launch Init.exe from Installer.exe, it won't work.
However, if there would be a way to execute the "jruby" commands in a new/different thread than the one that sets the environment variables, I think the problem would be solved. But I still couldn't find the way to do that.
Thanks.
NSIS doesn't have any threading. Apparently not quite true—but in your own code, you don't get to use threads.
You may need to set PATH for the current process; I'm not familiar with ${EnvVarUpdate}, but looking at its script it doesn't seem to updates the variable in the current process. Try this:
${EnvVarUpdate} $0 PATH A HKLM "${JRubyBinPath}" # The line you already have
System::Call Kernel32::SetEnvironmentVariable(t"PATH",tr0)
Another note: you are hard-coding JRubyBinPath; are you sure you really want to do that?
My NAnt builds run fine locally on a developer machine, and locally on the command line of the Hudson server, but they will not run in my configured Hudson project.
The console output when I run a Build via the Hudson web UI is similar to the following :
Started by user anonymous [workspace]
$ sh -xe
C:\WINDOWS\TEMP\hudson8104357939096562606.sh
C:\WINDOWS\TEMP\hudson8104357939096562606.sh:
fork failed: no error [1] Archiving
artifacts Finished: SUCCESS
I have another project configured properly that runs fine so I know the NAnt plugin is setup properly in Hudson, and that NAnt is on the system path.
Can anyone suggest possible causes as to why this build won't run?
The problematic build may be configured to Execute a Shell script, rather than Execute a Windows Batch file.
Copy the command from the existing build step (the Execute Shell Script) and remove the step. Then add a new step to Execute a windows Batch File and paste the command.
Trigger the build and observe the results.
(I asked and answered this since it took me quite a while to figure out how I had mis-configured this particular build. Hopefully it'll save time or give ideas to other people trouble-shooting automation..)
