Example 1 with DirectoryFileFilter

use of org.apache.commons.io.filefilter.DirectoryFileFilter in project che by eclipse.

the class JGitConnection method cloneWithSparseCheckout.

@Override

        files.stream().filter(File::isFile).forEach(file -> index.getEntry(file.getPath().substring(sourcePathLength)).setAssumeValid(true));
        index.write();
