How to use ecj with those changes? Or any other external tool by using
the executable configuration?
The compiler needs to implement the following interface (I think it is
the case of the Eclipse compiler, but didn't verified carefully):
javax.tools.JavaCompiler
That interface inherits a name() method, which returns a String. That
method needs to return a unique identifier. For the standard Java
compiler, that identifier is "javac". The javax.tools specification
recommends to use an identifier which is the same as the command invoked
on the command-line.
Then, the following file must be present in the JAR file and shall
contain the fully-qualified name of the JavaCompiler implementation (in
the future, we should allow to replace that requirement by a module-info
file).
META-INF/services/javax.tools.Tool
Finally, in the maven-compiler-plugin configuration declared in the
pom.xml file, the <compilerId> element shall contain the above-cited
identifier. The maven-compiler-plugin iterates over the tools using
java.util.ServiceLoader until it find a tool with a name matching the
compilerId. This mechanism is tested in the JUnit tests with two
`CompilerStub` implementations.
