Found instructions for configuring maven-compiler-plugin with ecj in [1]. Verified that ecj run in this way raises build errors when executed on commit d3ef5213. Define profiles "ecj" for using Eclipse compiler and "javac" for using javac including errorprone. By default ecj will be used. use ecj: $ mvn -Pecj clean install use javac: $ mvn -Pjavac clean install TODO: find out how to run ecj with errorprone from Maven.
