I am following the GeoEvent Developer Guide the part where you perform the mvn clean install to the sample-adapter.
(I am using Windows 10, apache-maven-3.8.1, Java 16, Eclipse Java EE)
I am having the following error:

I understand it must be something with the maven-bundle-plugin, but I am not sure how to fix it. Does anyone know? Thank you in advance.
Solved! Go to Solution.
It seems that the problem was the version of Java. With the version Java 8 works fine, also with Java 11.

This is due a bug in the BND tooling used to generate OSGi bundles, which came to light when JDK 15 came out and it started failing. The bug affects the Felix maven-bundle-plugin, which is used in many GeoEvent SDK samples and projects, and also the bnd-maven-plugin where it was first reported. See here for more info: bnd-maven-plugin ConcurrentModificationException on latest OpenJDK 15 EA · Issue #3903 · bndtools/bn...
I found that updating the Felix maven-bundle-plugin dependency to the latest 5.1.8 resulted in being able to build using JDK 17, and also worked at run-time in GeoEvent Server 10.8.1.
Keep in mind as well, you need to set maven.compiler.release=8 if you want to support < 10.9.x in addition to later versions (or it can be maven.compiler.release=11 if you will only be supporting 10.9.x and above).
