Similar to the mailing list thread at [1]http://gradle.1045684.n5.nabble.com/G... – I'm unable to run the findbugs task on my code due to this error in JDK 1.7:

[ant:findbugs] java.io.IOException: Cannot run program "C:\Program Files\Java\jdk1.7.0_02\jre\bin\java.exe": CreateProcess error=206, The filename or extension is too long

Or, with JDK 1.6:

[ant:findbugs] java.io.IOException: Cannot run program "C:\Program Files\Java\jdk1.6.0_21\jre\bin\java.exe": CreateProcess error=87, The parameter is incorrect

I'm using this version of gradle:

Gradle 1.0-milestone-8

Gradle build time: Monday, February 13, 2012 11:53:32 PM UTC
Groovy: 1.8.4
Ant: Apache Ant(TM) version 1.8.2 compiled on December 20 2010
Ivy: 2.2.0
JVM: 1.6.0_21 (Sun Microsystems Inc. 17.0-b17)
OS: Windows 7 6.1 amd64

When I run gradle with --debug, I can extract the command it runs when it tries to start FindBugs in a new JVM. I've abbreviated it in two places below:

14:32:46.933 [DEBUG] [org.gradle.api.internal.project.ant.AntLoggingAdapter] Execute:Java13CommandLauncher: Executing 'C:\Program Files\Java\jdk1.6.0_21\jre\bin\java.exe' with arguments:
(abbreviated from 120 files to 2)'C:\Users\chris\work\PAL-CPOF-SHELL\current\tasklearning\bridge\src\com\sri\pal\AbstractActionDef.java;C:\Users\chris\work\PAL-CPOF-SHELL\current\tasklearning\bridge\src\com\sri\pal\ActionDef.java'
(abbreviated from 166 files to 2)

It seems likely that this command line is simply too long for Windows to handle.

This fix will be part of the next release (1.0-rc1) that will hopefully be available within the next two weeks. We're currently working on a snapshot of this rc1 available to be tested in the field within the next days.
