gradle - Gradle:根据文件列表从目录中删除文件

Question

我目前正在尝试将旧的ant系统迁移到gradle。我对学习和学习还很陌生，所以也许这只是我忽略的琐碎事情。

我得到了一个名为delete.list的文件，其中包含我要删除的文件列表。

到目前为止，这是我的代码:

task deleteLib(type:DeleteFiles) {    
    deleteList = file("${buildDir}/delete.list")
}



 class DeleteFiles extends DefaultTask {

    @SkipWhenEmpty
    @InputFile
    File deleteList

    DeleteFiles()
    {
        description = 'Deletes Libs from Integris zip'
    }

    @TaskAction
    void delete(){
        def lines = deleteList.readLines()
        lines.each {
            delete fileTree(dir: "${project.buildDir}", include: "${it}")
        }
    }
}

delete.list:

lib/java/activation.jar
lib/java/pdfbox*.jar
lib/java/fontbox*.jar
lib/java/xmpbox*.jar
lib/java/jempbox*.jar
lib/java/iText*.jar
lib/java/itext*.jar
lib/java/jakarta-poi.jar
lib/java/commons-net*.jar
lib/java/jfreechart*.jar
lib/java/jcommon*.jar
lib/java/dom4j*.jar
lib/java/xmlbeans*.jar
lib/java/jaxen*.jar
lib/java/avalon-framework*.jar
lib/java/batik-all*.jar

稍作搜索后，我发现了此解决方案，因为在构建阶段我的_delete.list 可能不存在。

我当前的问题是gradle似乎与 fileTree方法有关:

* What went wrong:
Execution failed for task ':deleteLib'.
> Could not find method fileTree() for arguments [{dir=C:\entwicklung\Testumgebung\testProjectGradle\build, include=lib/java/activation.jar}] on task ':deleteLib' of type DeleteFiles.

有人知道我在这里缺少什么吗？

由于这两种方法都是在Project上定义的，并且groovy查找在task中定义的方法，因此您需要在project实例上显式调用这些方法:

project.with {
   delete fileTree(dir: "${project.buildDir}", include: "${it}")
}
