Build Path is Incomplete. Cannot Find....

[jamiecramb]

I can confirm that myself & three of my colleagues have also been seeing this issue while using STS 2.3.1 & 2.3.2 over the last few months.

To date we cannot find a specific pattern as to when the errors will appear / how to correctly resolve the issue (although we will try the workaround suggested by bcoffe)... sometimes a simple project clean / STS restart seems to fix the issue, other times doing bizzare things like installing & uninstalling plugins seems to resolve the issue but none of these work consistently.

It can quite often happen once we've done a fresh install of STS, created a new workspace, and then re-imported all of our existing projects.

In addition it sometimes requires a "fake edit" of the bean configuration files (select all, cut, save, paste, save) before the errors will disappear.

If you need any more info just give me a shout.

I can confirm that replacing the 2.3.2 versions of the following jars with the 2.3.0 versions provides a workaround for this issue in STS 2.3.2:

sts-2.3.2.RELEASE/plugins/org.springframework.ide.eclipse.aop.core_2.3.2.201 003220227-RELEASE.jar
sts-2.3.2.RELEASE/plugins/org.springframework.ide.eclipse.aop.mylyn_2.3.2.20 1003220227-RELEASE.jar
sts-2.3.2.RELEASE/plugins/org.springframework.ide.eclipse.aop.ui.matcher_2.3 .2.201003220227-RELEASE.jar
sts-2.3.2.RELEASE/plugins/org.springframework.ide.eclipse.aop.ui_2.3.2.20100 3220227-RELEASE.jar

Hi,

(sorry, I just back from vacation).

This error message is a bit strange as this should really be fixed in STS 2.3.2. In all my tests it is fixed and never occurred again. Could someone please provide steps to re-produce with a vanilla STS download? And maybe share a project that shows the issue.

Also replacing the aop 2.3.2 jars with the ones from 2.3.0 can't solve this issues because the 2.3.0 jars are API incompatible with required dependencies from 2.3.2 that are not replaced. So there is something else going on here as otherwise you guys would see a lot of NoSuchMethodErrors in your Error Log.

Regards, Christian

I have also installed STS 2.3.2 on Eclipse 3.4 under Windows and I am having the same problem.
Here the petclinic-servlet.xml and applicationContext-jdbc.xml is complaining missing class files (org.springframework.samples.petclinic.web.ClinicB indingInitializer, org.springframework.samples.petclinic.web.VisitsAt omView, org.springframework.samples.petclinic.jdbc.SimpleJ dbcClinic and org.springframework.samples.petclinic.aspects.Call MonitoringAspect) though it is in the src folder.

ttruong,

can you point to the sample project you are using? Maybe that I'm able to re-create.

Thanks,

Christian

I did the following to install STS 2.3.2:

1. Import the update sites from the bookmarks.xml (following the spring instructions)
2. I installed the 7 plugins from the site http://www.springsource.com/update/e3.5:
- Core / dm Server Tools
- Core / Spring IDE
- Core /STS
- Extensions (Incubation) / Spri
- Extensions / Spring IDE
- Extensions / STS
- Integrations / Spring IDE

3. In eclipse using svn I checked out the petclinic project from src.springframework.org/svn/spring-samples/petclinic/trunk
Once the project is in the workspace maven downloads all related dependencies.
At the end I am having the build path problems in those two xml files.

Cleaning the project didn't work but when restarting eclipse the error problem disappears. That is weird.

Have similar issue with STS 2.3.2. I was able to get rid of the issue by checking out to workspace missing projects "in the middle". Let me explain:

- Project A (uses classes in application context) from Project B
- Project B has dependency to Project C

In my workspace I had following projects:
- Project A
- Project C

After I checked out Project B to workspace and cleaning Project A - no more issues. I'm not sure how it works but maybe:

- Project A finds required class from Project B in JAR file,
- Project A tries to find class from Project C also in JAR file. Instead it should look for it in Eclipse project dependencies.

This is still happening in STS 2.7.1.RELEASE. @rience gave me the clue to just clean ALL of my projects and that cleared it up, but still annoying. Is there an issue filed for this already?

Hey!

Depending on what the problem really is. We have plans to upgrade m2e to the new Eclipse hosted version 1.0 in the near future, so that hopefully solve this.
