Build Eclipse Java Project from Command Line

Is there a way to compile an Eclipse-based Java project from the command line?

I’m trying to automate my build (using FinalBuilder not ant), and I’m neither a Java nor Eclipse expert. I can probably figure out how to do this with straight java command line options, but then the Eclipse project feels like a lot of wasted effort.

In the event that there is no way to compile an Eclipse project via the command line, is there a way to generate the required java command line from within Eclipse? Or are there some files I can poke around to find the compile steps it is doing behind the scenes?

Guys, I’m looking for an answer that does NOT include ant. Let me re-iterate the original question ……. Is there a way to build an Eclipse project from the command line?

I don’t think this is an unreasonable question given that I can do something like this for visual studio:

devenv.exe /build "Debug|Any CPU" "C:ProjectsMyProjectsourceMyProject.sln"



You can build an eclipse project via a workspace from the command line:

eclipsec.exe -noSplash -data "D:SourceMyProjectworkspace" -application org.eclipse.jdt.apt.core.aptBuild

It uses the jdt apt plugin to build your workspace automatically. This is also known as a ‘Headless Build’. Damn hard to figure out. If you’re not using a win32 exe, you can try this:

java -cp startup.jar -noSplash -data "D:SourceMyProjectworkspace" -application org.eclipse.jdt.apt.core.aptBuild


Several years ago eclipse replaced startup.jar with the “equinox launcher”

On Eclipse Mars (MacOX):

java -jar /Applications/ -noSplash -data "workspace" -application org.eclipse.jdt.apt.core.aptBuild

The -data parameter specifies the location of your workspace.

The version number for the equinox launcher will depend on what version of eclipse you have.
