如何用groovy markupbuilder創建帶特殊節點名稱的xml文檔

Question

我正在用groovy markupbuilder構建一個ant腳本。不幸的是MarkupBuilder的不允許我創建名爲「目標」（與targetee沒問題）節點， becauase它拋出我

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() 

所以我的MarkupBuilder裏面這個片段的工作：

targete(name: 'clean') { 
    delete(dir: rootProj.compilerOutput) 
} 

但我想達到同樣與「目標」節點..

我設法創建一個空的「目標」節點是這樣的：

builder.invokeMethod('target', [name: 'clean']) 

但我該如何繼續並在此「目標」節點內放置更多節點？

的工作代碼示例：

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 
    } 
}

如果我猜的沒錯，你的問題是你想創建屬於Groovy的關鍵字名節點？

如果是這樣，那麼你可以簡單地把在引號，像這樣：

def writer = new StringWriter() 
def builder = new groovy.xml.MarkupBuilder(writer) 

builder.project { 
    'for'(name: 'clean') { 
    delete(dir: '.') 
    } 
} 

println writer 

片斷代碼將打印出：

<project> 
    <for name='clean'> 
    <delete dir='.' /> 
    </for> 
</project>

對於我來說，這個工程：

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() 

你有target在調用之前設置爲代碼中的任何內容？

你可以嘗試：

builder.target(name: 'build-subprojects') { 

這可能會更好地工作？
