我正在使用groovy markupbuilder构建一个ant脚本。不幸的是,markupbuilder不允许我创建名为'target'的节点(对于targetstee没有问题), 因为它抛出了我
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()
所以在我的markupbuilder里面这个代码片段可以工作:
targete(name: 'clean') {
delete(dir: rootProj.compilerOutput)
}
但我想用'目标'节点实现相同的目标..
我设法以这种方式创建一个空的'目标'节点:
builder.invokeMethod('target', [name: 'clean'])
但我怎样才能继续在这个'目标'节点内放置更多节点?
工作代码示例:
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
}
}
答案 0 :(得分:3)
如果我猜对了,你的问题是你想创建名为Groovy关键字的节点吗?
如果是这样,那么您可以简单地将名称放在引号中,如下所示:
def writer = new StringWriter()
def builder = new groovy.xml.MarkupBuilder( writer )
builder.project {
'for'(name: 'clean') {
delete(dir: '.')
}
}
println writer
该代码片段将打印出来:
<project>
<for name='clean'>
<delete dir='.' />
</for>
</project>
对我而言,这有效:
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()
在调用此代码之前,您是否已将target
设置为代码中的任何内容?
你可以尝试:
builder.target( name: 'build-subprojects' ) {
这可能会更好吗?
我已经尝试过Groovy 1.7.5和1.8 beta 2并且无法让它失败: - /
