A typical project setup places the `gradle.properties` file in the root directory of the build.
Alternatively, the file can also live in the `<<directory_layout.adoc#dir:gradle_user_home,GRADLE_USER_HOME>>` directory if you want it to apply to all builds on your machine.

By default, the Gradle User Home (`~/.gradle` or `C:\Users\<USERNAME>\.gradle`) stores global configuration properties, initialization scripts, caches, and log files.

It can be set with the environment variable `GRADLE_USER_HOME`.

TIP: Not to be confused with the `GRADLE_HOME`, the optional installation directory for Gradle.

It is roughly structured as follows:

[listing]

├── caches // <1>
│   ├── 4.8 // <2>

        this.testOutputDir = testOutputDir;
    }

    /**
     * The variables to be used for replacing absolute paths in the iml entries.
     * For example, you might add a {@code GRADLE_USER_HOME} variable to point to the Gradle user home dir.
     * <p>
     * For example see docs for {@link IdeaModule}
