I created a simple project using "gdx-setup-ui.jar" and tried running all the projects. Android and desktop projects were running without any error. But when I launched the html project I got the following error. Any help??

I am using Win 7 and downloaded Junit 4.13 and hamcrest 2.1 from
https://github.com/junit-team/junit4/wiki/Download-and-Install
and put them in a folder named JUnit under C.
I have added the variable: JUNIT_HOME with value C:\JUnit.
I have also added the following to my classpath:
%classpath%;.;C:\Program Files\Java\jre1.8.0_171\bin;%CLASSPATH%;
%JUNIT_HOME%\junit-4.13-beta-1;.; %JUNIT_HOME%\hamcrest-core-2.1.jar;
Following https://github.com/junit-team/junit4/wiki/Getting-started,
I added the java files Calculator.java and CalculatorTest.java to my practice folder.
The command
javac -cp .;junit-4.13-beta-1.jar;hamcrest-core-2.1.jar CalculatorTest.java
is executed successfully. However, the command
java -cp .;junit-4.13-beta-1.jar;hamcrest-core-2.1.jar org.junit.runner.JUnitCore CalculatorTest
Fails, giving an error message like

Please note I have checked posts like java.lang.NoClassDefFoundError: org/hamcrest/SelfDescribing, but they have not been helpful. Could you please help?
The correct hamcrest jar is hamcrest-2.1.jar, not hamcrest-core-2.1.jar. You can download it from here.
According to mentioned guide it is assumed you have downloaded jars in the same package as your project:
Create a new folder junit-example and download the current
junit-4.XX.jar from JUnit's release page and Hamcrest to this folder.
If you decided to put jars separately probably you need to correct the command line correspondingly to take these jars files from %JUNIT_HOME%:
java -cp .;%JUNIT_HOME%\junit-4.13-beta-1.jar;%JUNIT_HOME%\hamcrest-core-2.1.jar org.junit.runner.JUnitCore CalculatorTest
Is there any option, how to make ScalaTest reporting into HTML file using Eclipse ScalaTest plugin?

I added all needed dependencies and it works - but - I dont think that this is correct behaviour.
Dependencies:
pegdown-1.1.0.jar
parboiled-core-1.0.2.jar
parboiled-java-1.0.2.jar
asm-all-3.3.1.jar
I downloaded the latest nightly and am trying to setup a project. I double click on the gdx-setup-ui.jar file but it does nothing. When I go to the commandline(as admin) and run :
java -jar gdx-setup-ui.jar
this is spit out

Things that I have already tried are:
uninstall and re-install jdk
restart computer
redownload all of the libgdx files
search google and stackoverflow
Try downloading an older version.
If it works properly without problems, then there might be some problem with nightly (which I believe would be fixed soon) otherwise the problem lies with your system.
This may not be a particular solution, but it'd narrow down the things to look for (error).
Good luck.
I am getting the follwoing error from Hudson. Could any one please tell me what is wrong here. My test cases are working fine.

This is because HUDSON is trying to parse your test results in file testresults.properties. It is getting a SAXParseException because testresults.properties does not contain valid XML. This is probably because you have no tests in your project.
OR because you have both HTMLs and XMLs (like I did). Make sure you only include *.xml.
All,
I am getting the com.mysql.jdbc.Driver exception when trying to load the Driver class using Class.forName("com.mysql.jdbc.Driver"). I have written a custom Eclipse plugin and wanted to access the database in my custom Eclipse plugin.
I have tried following 2 options, both obviously failed:
1 > Adding the mysql connection JAR file to the Eclipse plugin build path
2 > Adding the connector JAR file as library and adding to the plugin's runtime classpath
Can anyone please help me out on this?

I recommend to create your own OSGi-Bundle for the MySQL Driver, see http://wiki.eclipse.org/Create_and_Export_MySQL_JDBC_driver_bundle for a how-to. Afterwards you have to set a dependency in your plugin.xml of your bundle to the created mysql-bundle.
In addition: Please use in an OSGi environment not the DriverManager but an implementation of DataSource.
