Building Eclipse Java Projects from the Command Line
Composing Eclipse Java projects through the command line provides a convenient approach for automating build processes, particularly for non-Java or Eclipse experts. While ANT is frequently utilized for this purpose, there are alternative methods available.
Eclipse Headless Build
Eclipse provides a "headless build" functionality that enables project compilation without a graphical user interface. To initiate a headless build:
eclipsec.exe -noSplash -data "[workspace directory]" -application org.eclipse.jdt.apt.core.aptBuild
java -cp startup.jar -noSplash -data "[workspace directory]" -application org.eclipse.jdt.apt.core.aptBuild
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
Specify the appropriate workspace directory using the -data parameter. The Equinox launcher version varies based on the Eclipse version.
Generating Eclipse Command Line from Eclipse
If compiling via headless build is not feasible, you can generate the required Java command line from within Eclipse:
javac -cp [classpaths] [source files]
Include the required classpaths from the dependency libraries and specify the source files that need to be compiled.
