Error loading URCap to PolyScope

Hello,

Im developing a URCap and using an external .jar library (moka7). The project compiles but when I charge it to the PolyScope the URCap shows with a “!” sign and wont work. The .jar is uploaded to the resources file.

Thanks in advance!

Have you installed your .jar file and add it to the “Embed-Dependency” section? That did the trick in my case.

From the command line:
mvn install:install-file -Dfile= -DgroupId=“groupId” -DartifactId=“artifactId” -Dversion=“version” -Dpackaging=jar -DgeneratePom=true

Then you should have to add the line:
“Embed-Dependency"artifact”/Embed-Dependency"
in the section configuration/instructions

P.D. everything inside quotes is inside <>

Hello grodriguez,

I am not able to find out which are the values for groupId, artifactId or the version of my .jar.
Maybe it is because it originaly was a project that I got exported as a .jar to work with it as a library.

I sincerely appreciate your help anyway

You can open the .jar like a .zip file and, if it was a maven project, you could extract that information from the pom.xml.

I haven´t tested the case of importing a non maven project. But that seems a general java problem so you could search in sites like StackOverflow for more answers.

Solved! By just re-uploading the .jar file into de resources file did the trick! Thanks for your help grodriguez!
