Can't add String variable to my manifest - gradle

Question

I have a build.gradle file and I want to insert some variables into my manifest. This is what I have
def dateformat = new java.text.SimpleDateFormat("yyyy.MM.dd")
version = dateformat.format(new Date());
int userlimit = System.properties['user.limit'] == null ? 1 : System.properties['user.limit'] as int
def owner = System.properties['owner'] == null ? 'Demo version' : System.properties['owner']
task release(dependsOn: [jar, libs, obfuscate]) {
doLast {
def classesDir = new File('expanded-libs')
classesDir.mkdir()
configurations.embed.each {
println "Unzipping $it to expanded-libs.."
ant.unzip(src: it, dest: 'expanded-libs')
}
task combinedJar(type: Jar) {
from zipTree('build/foo-bar-pg-' + version + '.jar')
from configurations.embed.collect { println "Adding $it to the fat jar"; zipTree(it) }
archiveName "../foo-bar-${version}${outputFileNameSuffix}.jar";
exclude 'META-INF/*'
duplicatesStrategy 'EXCLUDE'
manifest {
attributes 'Implementation-Title': 'Foo Bar Module', 'Implementation-Version': version, 'User-Limit': userlimit, 'Licensed-To': owner
}
}
combinedJar.execute()
}
}
Now the interesting thing is that it works without the 'Licensed-To': owner piece, but somehow I can't use that variable in the manifest. For integers, it works, but owner is a String.
This is the error message I get if I run gradle release -Downer="foo" -Duserlimit=20
* What went wrong:
Execution failed for task ':release'.
> Could not find method task() for arguments [{type=class org.gradle.api.tasks.bundling.Jar}, combinedJar, build_36jmpdf
2mspiolilq5o7ipbd86$_run_closure14_closure27_closure29#547a8dfd] on task ':release'.
Can anyone help me how could I put String typed JVM arguments into my manifest?

You missed a closing } brace after the manifest attributes.
