android-cloud-build's Issues

`restore_cache` is unzipping the archive into directory with the name of `${key}`

Given KEY=myCache

Expected Behavior:

${BUCKET}/myCache.tgz would be extracted into ${SRC_DIR} without the myCache/ archive root directory.

Actual Behavior:

Unzipping the archive results in /workspace/myCache/.

I'm not sure why it's unpacked in /workspace rather than the root / because of the -C flag in the command here...but I'm not very familiar with tar 🤷‍♂

tar xpzf "$CACHE_FILE" -C /

Question:

The cache is saved and subsequently downloaded successfully. How can I restore it into (in my case) GRADLE_USER_HOME=/workspace/.gradle?

PS: This is slick 👍
