Re: [cdt-dev] Can't get CDT checked out in Eclipse to run

Hi Jonah, Jeff

 

I can get it working by reverting https://git.eclipse.org/r/#/c/132354/. Those Import-Packages are required for Java 11 support it appears.

 

(I’m using this JDK: https://adoptopenjdk.net/releases.html?variant=openjdk11&jvmVariant=openj9)

 

Regards

William

Jeff,

 

I am bringing in cdt-dev on this as Marc-Andre and Doug were involved in the earlier work on Java 11 and it's effect on freemarker/template plug-in. If there is still an open issue I we may need a bug report to continue the discussion in.

 

All, 

 

Jeff has been having trouble running CDT with Java 11 in the dev environment related to jaxb. If anyone has any input here I would be most grateful. If there is something that needs to be changed, we have only a couple days to resolve it without requiring a respin of 2018-12.

 

As it turns out, Ubuntu 18.04's Java 11 package is not really Java 11, so my earlier testing may have been fruitless. 

 

Thanks, 

Jonah

It turns out I am not using Java 11, or not exactly Java 11, despite what the package says:

 

 $ which java

/usr/lib/jvm/java-11-openjdk-amd64/bin/java

 

$ java -version

openjdk version "10.0.2" 2018-07-17

OpenJDK Runtime Environment (build 10.0.2+13-Ubuntu-1ubuntu0.18.04.4)

OpenJDK 64-Bit Server VM (build 10.0.2+13-Ubuntu-1ubuntu0.18.04.4, mixed mode)

 

$ apt-file search -x /usr/lib/jvm/java-11-openjdk-amd64/bin/java$

openjdk-11-jre-headless: /usr/lib/jvm/java-11-openjdk-amd64/bin/java

 

So I need to get a real Java 11 and try again :-(

Ok, thanks.  Roland said there is more to the workaround than simply bringing in com.sun.xml.bind.  He posted to

PTP regarding this workaround, but on the call, Alex isn't sure if both CDT and PTP using the work-around will cause

issues.

I'll see if I can reproduce with a clean dev workspace. Might not be for a few hours.

Sorry for the delay, I am in our weekly status call.

 

JREs has both 1,8 Openjdk and 1.11 Openjdk.  I have specifically chosen 1.11 and have also ensured that 1.8 execution and 1.11 execution point to it.

What does Installed JREs have? I wonder if something is getting confused if effectively a mismatch of versions is happening. If the Installed JREs (and the corresponding entry in the launch config) point to Java 11 fully and you are still having a problem then I can try creating a new dev workspace on my machine using Java 11 from the beginning and see if that works for me.

I verified that the FMGenerator has the fix in my parent Eclipse and that my parent can find JAXBException.  Interestingly, it points to both the Java 8 version in the JRE and

the loaded version (since I switched to Java 11 using alternatives).

 

I also tried deleting my bundle_pool from the parent Eclipse and restarting.  Still the same error in the child Eclipse (note that I cleared the workspace for the child Eclipse each time).

Hi Jeff,

 

I was able to with both OpenJDK8 and 11 (on Ubuntu 18.04) create new experimental Makefile project and I could see it stepped through FMGenerator.

 

The problem sounds like you have tools.templates without https://git.eclipse.org/r/#/c/131831/ however the version number in your stack trace indicates you have the right version. Can you provide the rest of the stack trace you have. As far as I can see, the only use of JAXBException is in FMGenerator. Does PDE find JAXBException? Are there any other errors in your log and does PDE validate the platform properly (in the lanuch config)?

 

You can try to blow away workspace/.metadata/.plugins/org.eclipse.pde.core/.bundle_pool/ so that PDE re-downloads the whole target.

 

Please let me know how you get on. I am sure there is more I can suggest, but I am at a loss now for what to do.

 

Jonah

Hi Jeff,

 

I can't look at this until the morning. I sure as hell hope I have been having it running as expected, but I have been playing around in so many version combinations. The error you are referring to does sound like the recently fixed up stuff for Java 11.

 

I'll make sure it is all right before I release RC2 tomorrow, and if it is working for me I'll let you know what I am doing so we can identify any differences. 

 

Thanks, 

Jonah

I have selected cdt.target as my workspace target, loaded and unloaded it different times.  It keeps geting this error.  I see you made a change but do you ever test with a child Eclipse running?
