It was working once but it crashed all of a sudden and now the above mentioned error!I am also using -Dorg.eclipse.swtbot.generator.enable=true option in arguments of run configuration. How to resolve this?


This Eclipse bug seems to match your error: https://bugs.eclipse.org/bugs/show_bug.cgi?id=416011. The bug talks about using SWTBOT with palette widgets.


I am not sure if this was the only option, may be i was missing something, but finally i used the following repo: http://download.eclipse.org/technology/swtbot/snapshots/#sthash.zMmLuzVs.dpuf
I got this from: http://planet.jboss.org/post/what_s_hot_for_swtbot
Well this worked for me.
Thanks #greg-449 for the info, it helped me. :)

The Eclipse version you are using doesn't understand the ASTParser version requested by the testng plugin (from the line numbers: probably AST.JLS8, see https://github.com/cbeust/testng-eclipse/blob/master/testng-eclipse-plugin/src/main/org/testng/eclipse/util/TestSearchEngine.java)
Try upgrading to an up-to-date Eclipse version, see https://www.eclipse.org/downloads/

Error drools - java.lang.NoClassDefFoundError: org/drools/event/KnowledgeRuntimeEventManager

I'm developing an eclipse plugin "jass" using the drools engine to make inferences on some concepts and displays them using an editor implemented with GEF
I added drools 5.5.0 in the build path. (knowledge-api.jar, drools-compiler.jar drolls-core.jar ecc.)
To test the operation of the engine I created a main method that retrieval engine and works well. Inverce if I run the plugin I get this error:

Can any one help how to solve this problem
Thanks

You might want to consider updating to Drools 6.x. The reason being that I assume an Eclipse plugin's runtime is an OSGI environment and I do not know if Drools 5.x is OSGI compatible, whereas Drools 6.x is definitely OSGI ready.

Eclipse Package Explorer Not Displaying Properly

When I select the "Package Explorer" tab, I get a vast white space with only the top of my 10 projects showing up, and not on the left side of the pane like it should, but instead on the right side. It's weird. If I click on it, I get a "Problem Occurred" pop box saying "An error has occurred. See error log for more details. Could not initialize class org.container.directory.Logger".
The error message in /.metadata/.log is this:

It appears to be related to org.container.directory.Logger. "Logging bundle must not be null." Anyone have any idea how to fix this? Thanks.

I haven't figured out how to fix it, but I have observed that it only occurs when I have a Servers project in my workspace - I suspect it has something to do with the fact that that project doesn't have a classpath...

There is the File DirectoryClasspathContainer_1.0.0_EclipsePlugin.jar in C:\Program Files\eclipse\plugins. Delete the file.

Thanks in advance for your answers

When you look at the error stack
at org.eclipse.wst.command.internal.env.common.FileResourceUtils.makeFolderPathAtLocation(FileResourceUtils.java:790)
at org.eclipse.wst.command.internal.env.common.FileResourceUtils.makeFolderPathAtLocation(FileResourceUtils.java:833)
at org.eclipse.wst.command.internal.env.common.FileResourceUtils.createFileAtLocation(FileResourceUtils.java:765)
It looks like there might be some discrepancy in creating a file/folder.
Check to see if the provided folder location exists.
If yes, then check to see if eclipse has enough permissions to create/write files/folder to the specified path.

Any solutions?

take a look at https://bugs.eclipse.org/bugs/show_bug.cgi?id=292199
This seems to be an old SWT bug with a long history.
Rarely reproducable and even harder to fix. (yet)
