Eclipse provides and uses its own compiler that is not javac![For For](/uploads/1/2/6/4/126450328/108454191.jpg)
The batch compiler class is located in the JDT Core plug-in. The name of the class is org.eclipse.jdt.compiler.batch.BatchCompiler. It is packaged into

You can control how progress is reported, or how the batch compiler is canceled, by subclassing the class org.eclipse.jdt.compiler.CompilationProgress.
Using the ant javac adapter![Eclipse Eclipse](/uploads/1/2/6/4/126450328/269971356.gif)
The Eclipse compiler can be used inside an Ant buildfile using the javac adapter. In order to use the Eclipse compiler, you simply need to define the build.compiler property in your buildfile.

So who all are using the Eclipse Java Compiler - besides developers using Eclipse for writing java code :) ? Apache Tomcat uses ECJ to compile JSPs, IntelliJ IDEA has support ECJ, as of GCJ 4.3, GCJ integrates with ECJ, Liferay Builds with ECJ, and there are many others.

The batch compiler class is located in the JDT Core plug-in. The name of the class is org.eclipse.jdt.compiler.batch.BatchCompiler. It is packaged into
plugins/org.eclipse.jdt.core_3.5.2.v_981_R35x.jar
. 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. To get them, go to the download page, select a build and search for the section JDT Core Batch Compiler. This jar contains the batch compiler and the javac ant adapter.Running the batch compiler from command line

Running the batch compiler programmatically
Use the static
compile(String commandLine, PrintWriter outWriter, PrintWriter errWriter, CompilationProgress progress)
method of the class BatchCompiler.
org.eclipse.jdt.compiler.CompilationProgress progress = null; // instantiate your subclass
org.eclipse.jdt.internal.compiler.batch.BatchCompiler.compile(
'-classpath rt.jar A.java',
new PrintWriter(System.out),
new PrintWriter(System.err),
progress);
You can control how progress is reported, or how the batch compiler is canceled, by subclassing the class org.eclipse.jdt.compiler.CompilationProgress.
