e4 on JavaFX with maven/gradle and java8 [message #1808197]

Hey,

i am just about to start a new application based on e4 on javaFX and i wanted to know if it is possible to develop an efxclipse application as a pure maven application or pure gradle application with java 8.

I found this repository doing all of this with java 11:

https://github.com/BestSolution-at/e4-efxclipse-maven-sample

I really like that approach. However i am unsure if all of this can also work with java 8 and i hope someone can tell me if i just would waste my time trying this out. I already tried the aforementioned example with java 8 but had no luck.

Thanks in advance.

Hey,

i was able to configure the mentioned project to work with java 8. Actually the problem was, that i had to locally build a needed dependency on maven-osgi-package-plugin.
I am able to start the application using the corresponding profiles and invoking a mvn clean install on the launch subproject.
Now a new problem arises when i try to add dependencies to one of the subprojects. I would like to add several org.apache.spark dependencies.
Unfortunately the compilation fails with the following error message:

[ERROR] Cannot resolve project dependencies:

Any hint on this would be greatly appreciated.

I also forked the mentioned project and added my adjustments there. The dependencies i have added can be found in the pom.xml of the xxx.lib subproject.
The project can be found here:

https://github.com/oemergenc/e4-efxclipse-maven-sample/

Thanks in advance.

You need to add those to the feature project as well

I wonder what you had to compile locally because that should not be required.

Hey,

thanks for your help. Unfortunately adding the dependencies to the feature project results in a new error message:

I added exactly the same dependencies to the feature product like to ones of the xxx.lib subproject.

Any further ideas?

Regarding the build i needed to do the following to get the build of this project to work:

git clone https://github.com/BestSolution-at/maven-osgi-plugin.git
cd maven-osgi-plugin
mvn clean install

Otherwise the build of the *e4-efxclipse-maven-sample* project did not complete successfully due to a missing dependency to maven-osgi-plugin.

Hey,

i think i have come a step closer to what i want. The problem here is, that these dependencies are not OSGI bundles.
Therefore i created a new subproject and modified the bnd.bnd file to include those dependencies as an OSGI bundle. For testing purposes i have added two dependencies,
one on org.osgeo.proj4j and one on a spark-core library. I am able to use classes from the proj4j library.
The code of that new subproject can be found here:

https://github.com/oemergenc/e4-efxclipse-maven-sample/blob/master/sample.mvn.parent/sample.mvn.spark/pom.xml

However whenever the spark-core library is included the application refuses to start with the following error message:

...

From here i have no clue where or what to investigate. The problem maybe that spark has a lot of transitive dependencies, some of them were included by bnd others not.
However any hint on what/where i could further investigate would be nice.

Thanks in advance.

If I had to guess I'd say eg the declarative services system did not start - I'll try to clone your project and have a look tomorrow

Well I took a look and the problem is caused by the fact that your spark stuff loads 2 bundles who conflict with those usd by efxclipse/e4. Unfortunately the launch code currently uses the maven resolver (who resolve transitive dependencies). So you need to exclude those in the launch/pom.xml

		<dependency>
			<groupId>sample.mvn</groupId>
			<artifactId>sample.mvn.feature</artifactId>
			<version>${project.version}</version>
			<exclusions>
            	<exclusion>
            		<groupId>javax.annotation</groupId>
    				<artifactId>javax.annotation-api</artifactId>
            	</exclusion>
            	<exclusion>
            		<groupId>org.glassfish.hk2.external</groupId>
    				<artifactId>javax.inject</artifactId>
            	</exclusion>
            </exclusions>
		</dependency>

Hey,

wow cool.
Can you tell me, how you debugged this so that i can do that myself next time?

Thanks in advance

I did not really debugged that one because I had the immediate idea that this is the problem and then the only thing I did was to do ss javax in the interactive console :-)
