Netbeans 6.8 Tree & editor hints not in sync with build

Question

I'm having two nb-projects. One nb-project(a) has the other nb-project(b) as a library dependancy.

Now both nb projects compile/build fine, but the hints for (a) are out of sync.

This interferes when i want to run/debug saying 'one or more projects were compiled with errors'

I've tried

• opening/closing both projects and recompiling
• scan for external changes'
• clean-build, removing the 'compile on save' flags for both projects etc.
• en/disabling 'Build Jar after compiling' for the jtools project.

Removing the :

./netbeans/6.8/var/index

directory only made things worse for the nb-project(a).. Now exclamation marks for all imports of packages from nb-project(b) But still compile/build worked fine. Even unit-tests within the same netbeans project in(b) didn't even recognize the root-package ?!

After some strugling its a bit better, but hints are still not correct in (a). Now in (a) it says one method doesn't exist in project(b), but i've looked it up in the build-jar of (b).. it's there !?

Any ideas how to get the hints back on track?

Thanks

Answer 1

I've seen something like this when I upgrade a library but neglect to remove an earlier incompatible version from a path visible to NetBeans. Older JARs carelessly left in an extension directory are particularly troublesome, especially if they alias new entries you've added elsewhere. Also, review the Tools > Libraries dialog entries for duplicates and errors. Finally, check each project to be sure it's using the required libraries.

There are three ways to create dependencies in NB. You can add a project, add a library, or add a jar/folder. Only the "Add Project" button tells NB that the dependency is mutable. The other choices (Library and Jar/Folder) expect the jar will never change.

Try deleting the dependency on project(b), then add it back using the Add Project button.

I only use the Add Library for stable, third-party libraries (apache commons for example). I only use the Add Jar/Folder for third parties libraries I know I won't use anywhere else. Such as vendor libraries for communicating with a particular device.
