accessing ant properties in groovy taskdef gives Null Pointer Exception
Question
I am trying to execute following code but I am getting null pointer exception.
<property name="from" value="from"/>
<property name="to" value="to"/>
<taskdef name="groovy"
classname="org.codehaus.groovy.ant.Groovy"
classpath="G:\Tibco_Training\groovy-binary-1.8.5\groovy-all-1.6.5.jar" />
<taskdef resource="net/sf/antcontrib/antlib.xml"/>
<groovy>
class MoveDir extends org.apache.tools.ant.Task {
//def from = 'from'
//def to = 'to'
public void execute() {
new File(properties.from).eachFileMatch ~/.*/, { file ->
file.renameTo(new File(properties.to , file.getName()))
println "Moving file: $file.name from: " + from + " to: " + to }
}
}
project.addTaskDefinition('movedir', MoveDir)
</groovy>
<movedir />
If I don't use ant properties in groovy then the code works fine, but when I use ant properties for specifying directories, then it give null pointer exception. Am I passing wrong values or wrong syntax is the cause.
No correct solution
OTHER TIPS
Wrong syntax, you have to use properties.'to'
and properties.'from'
