[gradle-user] CNFE while calling groovydoc witj 0.9

[Andres Almiray]

Hi all,

I've recently tried upgraded Griffon's build from 0.9-rc-2 to 0.9 but I'm 
getting a weird error

org.gradle.api.UncheckedIOException: Could not read entry ':buildDocs' from 
cache '/Users/aalmiray/dev/griffon/core/.gradle/0.9/taskArtifacts/cache.bin'.

the 'offending' code (from 
http://git.codehaus.org/gitweb.cgi?p=griffon-git.git;a=blob_plain;f=gradle/docs.gradle;hb=GRIFFON_0.9.X)
 is

task buildDocs(type: Groovydoc) {
    dependsOn { copyDocs }

    source = files("$buildDir/javadoc-src")
    destinationDir = "$buildDir/manual/api" as File
    docTitle = "Griffon $version"
    header = "Griffon $version"
    windowTitle = "Griffon $version"
    groovyClassPath = sourceSets.rt.classes + sourceSets.cli.classes + 
configurations.compile
    includePrivate = true
    use = true

    link('http://java.sun.com/j2se/1.5.0/docs/api', 
'java.,org.xml.,javax.,org.xml.')
    link('http://www.dpml.net/api/ant/1.7.0', 
'org.apache.ant.,org.apache.tools.ant.')
    link('http://junit.sourceforge.net/junit3.8.1/javadoc/', 
'org.junit.,junit.framework.')
    link('http://groovy.codehaus.org/api/', 'groovy.,org.codehaus.groovy.')
}


I was sure to clear any caches before running the build but got nowhere. Did 
something changed between 0.9-rc-2 and 0.9 regarding groovydoc or am I missing 
something obvious? The build was also upgraded to Groovy 1.7.6 but backing down 
to 1.7.5 yields the same result.

TIA
Andres
