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:

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