What is ECJ compiler?
ECJ, the Eclipse Compiler for Java, is an open source incremental compiler used by the Eclipse JDT. It is an option for Liferay builds and is in many cases faster than Javac or Jikes. The jar for ECJ is included in Liferay release 4.4. 0 and later.
What is ECJ in Linux?
DESCRIPTION. ecj is the batch compiler from Eclipse and is available as ecj. jar. Since 3.3, this jar also contains the support for jsr199 (Compiler API) and the support for jsr269 (Annotation processing). In order to use the annotations processing support, a 1.6 VM is required.
What is JDT compiler?
JDT Core is the Java infrastructure of the Java IDE. An incremental Java compiler. Implemented as an Eclipse builder, it is based on technology evolved from VisualAge for Java compiler. In particular, it allows to run and debug code which still contains unresolved errors.
What compiler does IntelliJ use?

Why does Eclipse use its own compiler ( ecj )?
Eclipse uses it’s own compiler (ECJ) to compile Java code. Debugging a program compiled with Eclipse is easier, because simple code changes can be applied instantly (by the hot code replacement). Maven on the other hand uses (by default) oracle JDK, that generates different byte code preventing hot code replacement in a Eclipse debug session.
Where can I get ECJ compiler for Java?
Since 3.2, it is also available as a separate download. The name of the file is ecj.jar. Its corresponding source is also available.
