Building Eclipse Java Projects from the Command Line

Question:

Is it possible to automate the build process of an Eclipse-based Java project using only command line tools?

Answer:

Yes, you can build an Eclipse project from the command line using the following steps:

1. Use the Headless Build Feature:

Execute the following command, specifying the path to your Eclipse workspace:

eclipsec.exe -noSplash -data "D:\Source\MyProject\workspace" -application org.eclipse.jdt.apt.core.aptBuild

This command uses the Java Development Tools (JDT) APT plugin to automatically build your workspace.

2. Use the Equinox Launcher (for Eclipse versions newer than Mars):

For newer versions of Eclipse, use the following command instead:

java -jar /Applications/Eclipse.app/Contents/Eclipse/plugins/org.eclipse.equinox.launcher_1.3.100.v20150511-1540.jar -noSplash -data "workspace" -application org.eclipse.jdt.apt.core.aptBuild

Replace the version number of the equinox launcher with the version appropriate for your Eclipse installation. The -data parameter specifies the workspace location.

Note: This method requires the JDT APT plugin to be installed in Eclipse. If it is not present, you can install it from the Eclipse marketplace.
