Caching

Information is cached in the /undefined/echo directory inside your Gradle Home (usually ~/.gradle or C:\Users\<USERNAME>\.gradle).

Server JAR

When BuildTools itself is installed, its version is cached inside a file called buildToolsVersion.json. When the project loads up, the cached BuildTools version is double-checked.

Any installed Server JARs are cached inside their own individual directory. Any log files will end up here as well.

Cleaning Cache

To clean the cache, you have two options:

1. Run the cleanCache task in Gradle. This will clean the entire cache, which might not be useful if you don't want to rebuild a number of versions.
2. Manually delete cached files and folders in GRADLE_HOME/undefined/echo. This is a dangerous process and could cause issues.
