Description Eddie Galvez

2010-10-19 16:26:35 EDT

Build Identifier: Eclipse 3.6.1

We have a headless instance of eclipse that includes in part:

org.eclipse.ant.core
org.eclipse.ant.launching
org.apache.ant

Trying to run a headless workspace build on a workspace project that has a new Ant Builder configured to run fails with the data shown below. Note that I do NOT check the "Set an Input handler" box, and I've also tried NOT checking the "Allocate Console" box.

Reproducible: Always

Comment 1 Darin Wright

2010-10-20 14:39:52 EDT

Reproduced. The problem is with a constant that was moved/re-created while fixing bug 264338.

The constants:

org.eclipse.ant.internal.launching.AntLaunching.SET_INPUTHANDLER
  value: "org.eclipse.ant.ui.SET_INPUTHANDLER"

org.eclipse.ant.internal.ui.IAntUIConstants.SET_INPUTHANDLER
  value: "org.eclipse.ant.uiSET_INPUTHANDLER"

Notice the latter (older, original) constant is missing a '.' (dot) separating the bundle name from the suffix. The default value for the constant is "true", so the tab updates the config with an attribute, but the launcher reads a different (non-existant) attribute and defaults to using an input handler.

Comment 2 Eddie Galvez

well well! Great... I saw that mispelt constant and I thought... well, maybe the developer was sloppy and just didn't have a "."...

I confirmed this fix is all good in 3.6.2 on our end as well
