Problem upgrading workspace to 3.5 [message #498494]

Please see this thread, I posted it in the JDT forum but it should really be here.

http://www.eclipse.org/forums/index.php?t=msg&th=157651& amp;start=0&S=4fece4e7d899144608c0a5745c0830ba

I had a project initially created with Eclipse 3.3, eventually moved to 3.4 with no problem, but 3.5 I get an issue with the referenced Java libraries. They don't show up in the project explorer.

Sorry Matt but I think this needs some elaboration.

I just downloaded the most recent build of Eclipse (Gallileo), I was previously using 3.4 and all was fine. The project I'm working on was originally created in an even earlier version (probably 3.3. but I don't remember). Anyway, I opened up my workspace in the new one and in my project (Java Web Project), I get this under my source directory.
Error: no label provider for org.eclipse.jst.servlet.ui.internal.navigator.Com

Max Hay replied:
I have precisely the same error message in the explorer view as Matt Rossner. In addition, I have a meaningless Error in the Problems view which has Path empty, Location "Unknown", and Type "Validation Message".
My Eclipse version is J2EE installed from eclipse-jee-galileo-SR1-win32.zip.
I am running under JDK 1.6 update 17.

Well I think it's pretty well described in the other post. Other than posting a screen shot I don't really see how much more I can elaborate on the problem. Maybe I'll post a screen shot later. Don't really have time now...

I am experiencing the same issue. I have re-downloaded eclipse-jee-galileo-SR1-win32.zip, checked-out an existing dynamic web project from CVS into a new/empty workspace, and still receive the same "Error: no label provider for org.eclipse.jst.servlet.ui.internal.navigator.Com" under the "Java Resources: src" treenode. I did not have this error until after upgrading from 3.4 to 3.5.

Not sure if this is related or helpful (full contents of log file)...

Choose "Package Presentation > Flat" and by happy

I am having this behaviour also and it is really getting on my nerves since I liked seeing my libraries under the Java Resource. It's not that it is a showstopper, but I would love to be able to see them like in the good old days.

This solution "works" but it does tell more about where the error is than being really helpful to me. With about 400 java classes my project gets very crowded when I present the packages in a flat manner.

For all that it's worth my project settings looks like so:

.project:

<?xml version="1.0" encoding="UTF-8"?>
<projectDescription>
	<name>CarAdmin</name>
	<comment></comment>

	</buildSpec>

		<nature>org.eclipse.wst.common.project.facet.core.nature</nature>
		<nature>org.eclipse.jdt.core.javanature</nature>
	</natures>
</projectDescription>

org.eclipse.wst.common.component:

<?xml version="1.0" encoding="UTF-8"?>
<project-modules id="moduleCoreId" project-version="1.5.0">
<wb-module deploy-name="CarAdmin">
<wb-resource deploy-path="/" source-path="/www"/>
<wb-resource deploy-path="/WEB-INF/classes" source-path="/src"/>
<property name="java-output-path" value="build/classes"/>
        <property name="context-root" value="/CarAdmin"/>
</wb-module>
</project-modules>

org.eclipse.wst.common.project.facet.core.xml:

<?xml version="1.0" encoding="UTF-8"?>
<faceted-project>
  <runtime name="Apache Tomcat v6.0"/>
  <fixed facet="jst.java"/>
  <fixed facet="jst.web"/>
  <installed facet="jst.java" version="6.0"/>
  <installed facet="jst.web" version="2.4"/>
</faceted-project>

and finally org.eclipse.jst.jsp.core.prefs:

#Tue Nov 03 11:42:34 CET 2009
eclipse.preferences.version=1
jsp-content-type/<project>=text/html
jsp-language/<project>=java

I'd be helpful to provide more information as needed to help solve this riddle

Edit: bad typo

Interesting... if I switch my package presentation to Flat (no error there, but not desirable for large projects), then back to Hierarchical, the Libraries tree node appears and works fine (no error node) until I exit Eclipse and relaunch. Bug?

Did you resolve your problem?

I also have 2 miningless errors on a project with no description, no path, Location Unknown, Type Validation Message.

In my case even with flat presentation the errors don't go away.

My project references two other projects. When the two are selected as Java EE dependency I have the errors. If I deselect one of them than I have no errors.

Also these errors aren't causing any problems when compiling, exporting or deploying the project.

It does not sound like you are having the same error as the one discussed in this thread. Are you sure your problem is with the viewing the libraries included in the project?

Hmmm... I created a new source folder called /test for my unit tests, and the error node has gone away.

projectname/src
projectname/test

Alright,
but if you remove that additional source folder, you are back. Another workaround is to 'customize view...' and deselect Empty parent package, so it will be shown. Then it is possible to use nice Hierarchical presentation.

Anyway, this is serious JDT? bug to me, because if the '.project' is desired to be in the repository (in unified environment e.g.), you cannot simply checkout and go because error appears also in such case, BUT it can be checked out using wizard to create new project...

Good to see some tips about how to work around this problem, but it still doesn't solve the underlaying problem.

I would like to find a soltion I could do that would make this not happen whenever someone checks out my project from Subversion. If this solution is a bugfix not coming untill next major version, then so be it.

I forgot about this post, good to see some work arounds at least. I've just stuck to Ganymede since I originally posted this but I may try to upgrade again. Thanks.

Enabling Maven Dependencies solved that problem for me. Just remember to unable Maven Dependencies under Your Project -> Right-Click -> Maven -> Enable...

In my case, I was resolved in this way.

right click on project > "properties" > "Deployment Assembly" > Remove "Maven Dependencies"

No, this is just stupid workaround. Confused

The source of the problem is that you have copied your necessary libraries under src/main/webapp/WEB-INF/lib, and maven want to copy libs again to the same place under target.

So you have to delete your libs from src/main/webapp/WEB-INF/lib directory, and let maven manage them. Very Happy
