Unable to build example with Java 11

Hi, I am trying to run the example with Java 11 but I can't make it work. Even after updating the example's version for the artifact 'at.bestsolution.efxclipse.rt.release' from '3.5.0-SNAPSHOT' to '3.6.0' I cannot run the program:

Any ideas on how to make this work? Thanks!

what maven version are you running that on?

Hi Tom, Thanks again for your help. Here is the info: mvn --version Apache Maven 3.6.0 Maven home: /usr/share/maven Java version: 13.0.2, vendor: AdoptOpenJDK, runtime: /usr/lib/jvm/adoptopenjdk-13-openj9-amd64 Default locale: en_US, platform encoding: UTF-8 OS name: "linux", version: "5.4.28-050428-generic", arch: "amd64", family: "unix"

IIRC Maven 3.6.0 and tycho don't like each other please use maven 3.5.x or better upgrade to maven 3.6.3

I still have the same problem:

mvn --version Apache Maven 3.6.3 (cecedd343002696d0abb50b32b541b8a6ba2883f) Maven home: /opt/maven Java version: 13.0.2, vendor: AdoptOpenJDK, runtime: /usr/lib/jvm/adoptopenjdk-13-openj9-amd64 Default locale: en_US, platform encoding: UTF-8 OS name: "linux", version: "5.4.28-050428-generic", arch: "amd64", family: "unix"

` mvn -f launch/pom.xml test -P netbeans

hm i think the Readme.md is wrong. You first need to run mvn clean install followed by mvn -f launch/pom.xml test -Pnetbeans - looking at the change history the modifications have been contributed by @FlorianKirmaier

Well, I guess it was both things, because with maven 3.6.0 installed I kept getting the same error. Now that I tried with 3.6.3 it works from the command line. When trying to run it from Eclipse with the MVN OSGi Launcher, I get a NullPointerException but nothing more than that:

An internal error occurred during: "Launching Sample". java.lang.NullPointerException Edit: After opening the dependent projects, all of them have an error marked in their pom.xml files:

Plugin execution not covered by lifecycle configuration: biz.aQute.bnd:bnd-maven-plugin:3.4.0:bnd-process (execution: default-bnd-process, phase: process-classes)

Could this problem be related to this: https://github.com/bndtools/bnd/issues/2904 ?

I am getting closer. I decided to start from scratch (even uninstalled eclipse). After cloning the project, installing the maven dependencies and running maven clean install, I can run the program from eclipse by executing the 'Sample' run configuration.

If I modify anything, llike adding the following to the parent pom's properties section: <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> then saving, updating the maven project and refreshing the project, when I try to run the project again by executing the 'Sample' run configuration I get the following error:

osgi> An error has occurred. See the log file
/tmp/launch/configuration/1586993487349.log.

Of course the log file doesn't give me any more information that the console output.

Maybe this is the reason I have been hitting my head against the wall so many times trying to run the app from Eclipse.

By the way, it always runs fine from the command line (even after editing a file) when I use:

mvn -f launch/pom.xml test -Pnetbeans

What is going on inside Eclipse? Shouldn't be editing a single file a relative painless process? Am I missing anything? Thanks!

To run from inside Eclipse you don't have to do a mvn clean install. On the resolve errors:

openjfx.graphics.mac is fine as you are on Linux
openjfx.graphics.win32_64 is fine as you are on Linux
org.osgi.service.component.annotations is fine as this is only needed at compile time

So we are left with the org.eclipse.fx.osgi which is not good as it says it can not find the osgi-framework. I'll see if I can find the time to run that stuff myself.

I just tried it myself and it works perfectly fine for me - I'm on Eclipse "2019-12" but I doubt this makes a difference

Hi Tom, Thanks for taking the time to look into this. It is driving me insane. I have two specific questions for you:

What are the necessary steps to run the project within Eclipse right after I clone the git repository?
What are the necessary steps to run the project after doing modifications? After I cloned the project from git and installing the dependencies from the instructions, the only way I could make the project launch was to select 'sample.mvn.parent' right click, run as 'maven clean', followed by 'maven install' and lastly executing the maven-osig 'Sample' run configuration. Am I am doing something wrong here? Also, just in case, the error I happened running both the eclipse embedded maven (v3.6.3) and the 3.6.3 that installed in my system that builds and launches the program with no issues from the command line... If this is related to Eclipse's maven support (and I found countless complains in the internet regarding errors), I was wondering if you knew of anyone trying Gradle to run the project (I know you mentioned you don't use it, but if I ever get this to work with it, you'll be the first to know). Anyway, thanks again!

Hi again Tom. I don't know why this keeps happening to me. It is always a new error and they happen randomly. Sometimes the build is fine, sometimes it fails. Now it is failing again from the command line:

The worst part is that I see the artifacts in your repository. I even deleted the local maven cache, but still no luck.

does that still happen?

This is not happening anymore... I will close it for now and reopen it if does.
