java - Build multi-platform executable for a SWT application (Eclipse) -


i have eclipse-based swt application, not using maven.

my application targets multiple operating systems (centos, windows, , mac).

the jar file not os agnostic swt library, specific each os type, not mention processor type (x86 and/or x64).

i saw other issue, targets maven , not using maven.

i have "org.eclipse.swt" added project following outlined procedure , including entire swt downloaded zip file. specifies second project in package explorer.

earlier when including swt.jar, bit easier, had delete jar, include new one, , rebuild, a pain. use entire swt zip, process bit tedious , not professional.

what steps, when specify "right click > java > runnable jar file" create single executable jar 3 (or many) different jar files, 1 per operating system? visual studio nicely, not know how here in eclipse.

update: answer comment, wanted add jface support, want use tableviewer feature, requires jface. eclipse has this page outlining in first part how add in swt. steps work except adding source code @ end, off-topic.

i followed steps 64-bit windows, have support centos , mac "would nice" @ moment.

independent of swt.jar verses org.eclipse.swt, clean way (think visual studio .net) build single runnable/executable jar file application, 1 per supported os type. thought specify build (whatever menu key sequence after set things up) , 1 single executable jar file per target os.

right, despite me saying can create single .jar file platforms, wasn't able working properly.

however, managed example project , running create separate .jar file each platform using ant.

you can download whole project here.

the build script looks this:

the project nothing fancy, jface dialog show jface works well.

note:

to make compile on windows machine, have change 1 line:

<fileset dir="${lib.deploy.dir}" includes="**/swt_linux_gtk_x86.jar" />

change to:

<fileset dir="${lib.deploy.dir}" includes="**/swt_win32_x64.jar" />

or

<fileset dir="${lib.deploy.dir}" includes="**/swt_win32_x86.jar" />

basically, line has represent system, i.e., system you're compiling on.
