Thank you Evan for fixing the issue.
Now I have a compilation problem (I’m using Eclipse IDE) in the DefaultDataContextPluginTest class:
Description Resource Path Location Type
DefaultDataContextPlugin cannot be resolved to a variable DefaultDataContextPluginTest.java /orekit/src/test/java/org/orekit/compiler/plugin line 72 Java Problem
I think this problem occurs because the compiler package (folder src/main/java/) is excluded in the pom file.
There is another problem in the DataProvider class (see Jenkins output ). I think the problem is generated because the method feed (with 3 arguments) just calls the method feed (with 2 arguments). However, the method with 2 arguments has a @DefaultDataContext annotation. So, I think we have to add a @DefaultDataContext annotation to the default implementation of the feed method (with 3 arguments).
I prefer asking you before because I’m not familiar with this new feature
