Version 25.0 on Maven Repository

[Gustominox]

Hey, is there any timeline on version 25.0 being available on the maven repository?
I'm using eclipse mosaic for a university project and the mismatch between version 24.1 and the java_docs is giving me headaches.

Any help would be greatly appreciated!

Thanks for pointing that out! In fact, the version 25.0 has been deployed to the maven repository already two week ago. However Eclipse had massive IT problems last week which required them to role out rather old backups. Apparently, 25.0 was removed from the repo by doing so, even 24.1 is not there anymore 😞. Another bad news is, that we don't have the possibility to deploy the missing jars right now, since the only way to do so is via Eclipse CI instances, which are still offline as we speak. So the only possibility for you would be, to clone our git repository and install the jars for yourself locally:

git clone --branch 25.0 --single-branch https://github.com/eclipse-mosaic/mosaic.git
cd mosaic
mvn clean install -DskipTests

Please also tell us if we could improve anything to make working with the software easier for you.

Thank you for the fast reply!! After installing the jars myself is there a best way how i can reference it in the pom.xml for my project?

I typically use the following pom.xml in conjunction with this folder structure:

+ etc
| +- hosts.json
| +- logback.xml
| \- runtime.json
+ scenarios
| \- MyScenario
|    +- ...
|    \- scenario_config.json
+ src
| \- main
|    \- java
|       \- my   
|          \- package
|             \- MyApplication.java
\- pom.xml

The pom.xml

When I load that into IntelliJ IDEA, I can use the following run configuration to start the scenario located in the scenarios directory:

For my purposes this worked, I'm probably missing some maven knowledge here, i thought it was gonna be somehow different 😅

<dependencies>
      <dependency>
          <groupId>org.eclipse.mosaic</groupId>
          <artifactId>mosaic-application</artifactId>
          <version>25.0</version>
      </dependency>
</dependencies>

Then i run mvn clean package and use the .jar in my scenario.

If you just want to compile against the mosaic-application API, this is 100% the way to go :) If you want to execute everything from the IDE to make things easier (e.g., no need to execute mvn or copy the jar anymore), then you can try to adapt the shown approach. This also allows you to debug everything using breakpoints.

[Gustominox]

Yeah your way is better especially to take advantage of the debugging tools. I just had a quick setup of the project and started developing, definitely gonna try it like that tho 😄.
