Android Studio – Unable to Merge from SVN Branch

Merging branches in SVN using Android Studio can sometimes be a challenging task. This article addresses common scenarios where you might encounter difficulties merging from an SVN branch.

Common Issues and Solutions

1. Conflicts during Merge

Conflicts arise when changes in the branch you are merging from overlap with changes in your local working copy. This can lead to merge errors.

Steps to Resolve Conflicts:

• Android Studio will highlight conflicted files in the “Changes” view.
• Open the conflicted files and review the changes.
• Choose the desired changes – “Yours” (your local changes), “Theirs” (changes from the branch), or “Merged” (a combination).
• Save the resolved files.
• Commit the changes to your local repository.
• Attempt to merge again.

2. Uncommitted Changes in your Local Workspace

If your local workspace has uncommitted changes, Android Studio might refuse to merge from the branch.

Steps to Resolve:

• Commit all pending changes in your local workspace.
• Attempt to merge again.

3. Incorrect Branch Selection

Ensure you are merging from the correct SVN branch. Mistakes in branch selection can lead to unexpected results.

Steps to Verify:

• Double-check the branch name you are merging from.
• Confirm the branch is the intended branch for the merge.

4. Outdated Local Repository

If your local repository is not up-to-date with the latest changes from the remote SVN server, merging can fail.

Steps to Update:

• Update your local repository to the latest version.
• Attempt to merge again.

5. SVN Server Connectivity Issues

Network issues or server downtime can cause problems during merging.

Steps to Check:

• Verify your connection to the SVN server.
• Check for any network outages or server issues.

Example: Resolving Conflicts

Imagine you are merging a feature branch (“feature_branch”) into your “main” branch. You encounter a conflict in the file “MainActivity.java”.

Conflict Scenario:

<<<<<<< HEAD
// Your changes in the "main" branch
=======
// Changes from the "feature_branch"
>>>>>>> feature_branch

Resolving the Conflict:

// Choose either "Yours" or "Theirs"
// In this example, we choose "Theirs"
// Changes from the "feature_branch"

Committing the Resolved Changes:

// Commit the resolved conflict in Android Studio
// Message: "Resolved conflict in MainActivity.java"

Continuing the Merge:

// Re-attempt the merge operation
// The merge should now succeed
