我正在尝试使用Spock模拟下面的java方法。
public List<DiffEntry> listDifferences(String oldCommit,String newCommit,Git git)
throws GitAPIException,RevisionSyntaxException,AmbiguousObjectException,IncorrectObjectTypeException,IOException {
logger.info(
"Inside DiffCommits#listDifferences to calculating difference commits refs {} and {} ",oldCommit,newCommit);
ObjectId oldTree = git.getRepository().resolve(oldCommit);
ObjectId newTree = git.getRepository().resolve(newCommit);
if (oldTree == null || newTree == null) {
logger.warn(
"Could not resolve either old {} or new commits {},difference cant not be calculated",newCommit);
throw new RefNotFoundException("Unable to resolve tag reference. Invalid tag provided");
}
ObjectReader reader = git.getRepository().newObjectReader();
CanonicalTreeParser oldTreeIter = new CanonicalTreeParser();
oldTreeIter.reset(reader,oldTree);
CanonicalTreeParser newTreeIter = new CanonicalTreeParser();
newTreeIter.reset(reader,newTree);
DiffFormatter df = new DiffFormatter(new ByteArrayOutputStream());
df.setRepository(git.getRepository());
List<DiffEntry> entries;
entries = df.scan(newTreeIter,oldTreeIter);
df.close();
if (logger.isDebugEnabled()) {
for (int i = 0; i < entries.size(); i++) {
logger.debug("Entry: " + entries.get(i));
}
}
return entries;
}
一切正常，但以下代码的模拟失败
DiffFormatter df = new DiffFormatter(new ByteArrayOutputStream());
在
处出错df.setRepository(git.getRepository());
我得到的错误是

> cast to org.eclipse.jgit.diff.DiffConfig java.lang.ClassCastException:

任何帮助将不胜感激
