Exception in running C language

[salmassari]

Hi RefDiff Team,

I've been facing an issue while running and mining C project.

The code:

CPlugin cPlugin = new CPlugin();
	RefDiff refDiffC = new RefDiff(cPlugin);
	
	File gitRepo = refDiffC.cloneGitRepository(
		new File(tempFolder, "htop"),
		"https://github.com/htop-dev/htop.git");
	
	printRefactorings(
		"Refactorings found in:",
		refDiffC.computeDiffForCommit(gitRepo, "0750ff7e76d845a70749cc00fa25dbe98a7147a1"));

The exception:
Exception in thread "main" java.lang.RuntimeException: java.lang.SecurityException: class "org.eclipse.cdt.internal.core.dom.parser.c.GNUCASTGotoStatement"'s signer information does not match signer information of other classes in the same package

I think it would be solved by a jar file. I've tried to check all possible jars but still no one effect on parsing.

I have solved my issue by commenting implementation 'com.github.aserg-ufmg:refdiff-c:2.0.0' and uncommentting "implementation project(':refdiff-c')" in build.gradle. Now I can run it for the git repo.
