How to find the current git branch in a plugin Follow

The code is this:

List<GitRepository> repositories = GitUtil.getRepositoryManager(e.getProject()).getRepositories();
if (repositories.size() > 0){
    System.out.println(repositories.get(0).getCurrentBranch());
}

Assuming you are using intellij community edition to build your plugin, you will need to add the following:

/snap/intellij-idea-community/185/plugins/git4idea/lib/git4idea.jar

( you can check the path for other jars in this window )

To:

File > Project Structure >  SDKs > Intellij IDEA Community Edition IC-XXX.XXXX.XX > Classpath

Also, you will need to add the following to plugin.xml:

<depends>Git4Idea</depends>
