how to create xml document with special node names with groovy markupbuilder - groovy

Question

I am building an ant script with groovy markupbuilder. Unfortunately markupbuilder doesn't allow me to create nodes with name 'target' (no problem with targetee),
becauase it throws me
Caught: groovy.lang.MissingMethodException: No signature of method: java.lang.String.call() is applicable for argument types: (java.util.LinkedHashMap, BuildGen$_main_closure1_closure5) values: [[name:clean], BuildGen$_main_closure1_closure5#18efaea]
Possible solutions: wait(), any(), trim(), split(), dump(), next()
so inside my markupbuilder this snippet works:
targete(name: 'clean') {
delete(dir: rootProj.compilerOutput)
}
but I would like to achieve the same with a 'target' node..
I managed to create an empty 'target' node this way:
builder.invokeMethod('target', [name: 'clean'])
but how can I go on and put more nodes inside this 'target' node?
Example of working code:
def writer = new StringWriter()
def builder = new groovy.xml.MarkupBuilder(writer)
builder.project(name: projectName, basedir:'.') {
// works with 'target2' but not with 'target'
'target2'(name: 'build-subprojects') {
rootProj.getAllDependentProjects().each { p->
echo(message: "Compiling project: ${p.projectName}")
// some real stuff
}
}

If I guess right, your problem is you want to create nodes with names that are Groovy keywords?
If so, then you can simply put the name in quotes, like so:
def writer = new StringWriter()
def builder = new groovy.xml.MarkupBuilder( writer )
builder.project {
'for'(name: 'clean') {
delete(dir: '.')
}
}
println writer
That snippet will print out:
<project>
<for name='clean'>
<delete dir='.' />
</for>
</project>
For me, this works:
def projects = [ 'pro_one', 'pro_two' ]
def writer = new StringWriter()
def builder = new groovy.xml.MarkupBuilder(writer)
builder.project( name: 'test', basedir:'.' ) {
'target'( name: 'build-subprojects' ) {
projects.each { p ->
echo( message: "Compiling project: ${p}" )
}
}
}
println writer.toString()
Have you got target set to anything in your code before calling this?
You could try:
builder.target( name: 'build-subprojects' ) {
That might work better?
I've tried Groovy 1.7.5, and 1.8 beta 2 and can't get it to fail :-/
