回答1:

Clean your maven repository:

(By default in your user folder)

~/.m2/repository

Then perform a clean install so it download the dependencies again and recompile your entire project:

mvn clean install

回答2:

ClassFormatError: Truncated class file

means that one of the class file is corrupted. Try to run clean goal to do the bad classes cleanup before you run the install target. Or simply combine both the targets and do mvn clean install for your project.

回答3:

I can see from your stac-trace that you are using reflection. Is the class working when you use it normally? Is it possible that when you use reflection, the class is unreachable or mis-used?
