PDE build workspace location [message #881581]

I notice that PDE headless builds make use of the directory "workspace" in the user's home directory. This can cause a conflict if the same directory is being used for development with Eclipse.

If the directory doesn't exist, the PDE build creates it. That's good, since to make sure I get a clean build, I'll delete any existing "workspace" directory.

Is there a way to configure the location of the "workspace" directory the PDE build uses? And what part of the build process is creating it, anyway?

Some part of the pde build plugins used by the pde build tasks must reference the Instance location (the workspace). You're using org.eclipse.ant.core.antRunner to run your build, right?

As a workaround you could try launching your build with: -data $HOME/buildWorkspace

Yes, I'm using org.eclipse.ant.core.antRunner.

And thanks, your suggestion works.

What program uses "-data"? I haven't been able to find it documented anywhere.

Another workaround I found was to define "user.home" to the JVM with "-Duser.home=somedirectory", but using the "-data" option is better since it lets one specify the workspace directory name. Defining "user.home' changes the location of the workspace directory, but not its name.

Hi Glenn,
I'm not aware that PDE headless build uses workspace (in sense of
workspace that you are choosing at the Eclipse IDE launch time).

It's a bad practice to share this folder for both Eclipse IDE and PDE
headless build.

You should always prefer to copy features and plugins comprising your
project out of Eclipse workspace (or check it out from SCM) to folder
specified in "baseLocation" PDE Build property
(http://help.eclipse.org/indigo/topic/org.eclipse.pde.doc.user/tasks/pde_product_build.htm
and in particular
http://help.eclipse.org/indigo/topic/org.eclipse.pde.doc.user/reference/pde_builder_config.htm).

The PDE builder uses a directory named "workspace" in ${user.home} to copy some info about plugins its using. If the directory doesn't exist, it's created.

Agreed, and that's why I wanted a way to specify exactly where the PDE build workspace is, so that building was controlled and wasn't affected by other things.

There are two ways.

1. Use "-data" to explicitly specify a directory, which by the way, doesn't need to be called "workspace".

2. Set the property "user.home" on the command line. The workspace directory used will be "${user.home}/workspace".

That's part of the standard eclipse framework set of options.

You can see -data and others at http://help.eclipse.org/indigo/index.jsp?topic=%2Forg.eclipse.platform.doc.isv%2Freference%2Fmisc%2Fruntime-options.html
