[NOTE]
====
IntelliJ currently ships with an outdated version of the Eclipse Compiler for Java (ECJ), which does *not* support Java 21 or later. Therefore, Scout {scout-version} requires *Eclipse Compiler 3.40.0*.

To use ECJ 3.40.0 in IntelliJ:

* https://repo1.maven.org/maven2/org/eclipse/jdt/ecj/3.40.0/ecj-3.40.0.jar[Download ECJ 3.40.0]
* In IntelliJ, go to:
+
`File | Settings | Build, Execution, Deployment | Compiler | Java Compiler`
* Under *Eclipse Options*, set *Path to ECJ batch compiler tool* to the downloaded `ecj-3.40.0.jar` file.
