PathAlreadyExists

Error message

PathAlreadyExists

What it means

PathAlreadyExists is thrown by AbstractDirectory.createDir when the directory being created already exists in the abstract dirs map. The library treats duplicate creation as an error rather than returning the existing directory.

Solutions

1. Check containsDir(path) before calling createDir and reuse the existing Directory via getDir.
2. Wrap createDir in try-catch for PathAlreadyExists and fetch the existing dir with getDir(path) in the catch block.
3. Restructure loops so each unique path is created only once (dedupe with a Set).

Example fix

// before
Directory dir = root.createDir("res/values");
// after
Directory dir = root.containsDir("res/values")
    ? root.getDir("res/values")
    : root.createDir("res/values");

boolean exists = dir.containsDir(path);

try { return dir.createDir(path); } catch (PathAlreadyExists e) { return dir.getDir(path); }

When it happens

Trigger: Calling createDir(path) twice on the same AbstractDirectory for the same path, or calling createDir on a path that already exists in the loaded tree (e.g. res/values already loaded from the APK/zip).

Common situations: Re-running a resource-obfuscation pipeline on a directory object that already loaded all entries; looping over resource names where the same parent dir appears multiple times.
