JGit failure in Cloning repository

Question

I am currently facing an issue in JGit with Cloning repository. I used CloneCommand object to clone a my own public repository but it failed. I got these messages from a ProgressMonitor

-remote: Compressing objects
-receiving objects
-resolving deltas
-Checking out files [And here app crashed]

I used the following code to clone repository

ExecutorService executor = Executors.newSingleThreadExecutor();

        final Handler handler = new Handler(Looper.getMainLooper());

        executor.execute(

                new Runnable() {

                    @Override

                    public void run() {

                        try {

                            Log.e("GitDebug",file.getAbsolutePath());

                            Log.e("GitDebug",username);

                            // Log.e("GitDebug",password);

                            Log.e("GitDebug",url);

                            CloneCommand clone = Git.cloneRepository();

                            clone.setURI(url);

                            clone.setDirectory(file);

                            clone.setBare(false);

                            clone.setCloneAllBranches(true);

                            if (setUseCredentialsProvider) {

                                // clone.setCredentialsProvider(new UsernamePasswordCredentialsProvider(username, password));

                            }

                            clone.setProgressMonitor(

                                new ProgressMonitor() {

                                    @Override

                                     public void start(int arg0) {}

                                     @Override

                                     public void beginTask(String arg0, int arg1) {

                                         gitCallback.onProgress(arg0,arg1);

                                     }

                                     @Override

                                     public void update(int arg0) {}

                                     @Override

                                     public void endTask() {}

                                     @Override

                                     public boolean isCancelled() {

                                         return false;

                                     }

                                     @Override

                                     public void showDuration(boolean arg0) {}

                            });

                            clone.call();

                            gitCallback.onProgressComplete(true, "Download complete");

                        } catch (GitAPIException | JGitInternalException e) {

                            gitCallback.onProgressComplete(false, e.getMessage());

                        }

                    }

                });

Here is the crash message:

java.lang.NoSuchMethodError: No virtual method transferTo(Ljava/io/OutputStream;)J in class Ljava/io/InputStream; or its super classes (declaration of 'java.io.InputStream' appears in /apex/com.android.runtime/javalib/core-oj.jar)

InGradle

compileOptions {

    }
....
implementation 'org.eclipse.jgit:org.eclipse.jgit:6.5.0.202303070854-r'

I there any way to fix this error?

Answer 1

InputStream.transferTo was added in API level 33. You need to use at least API level 33.
