在Gradle构建脚本中,重复的代码量正在增加。除了几行之外,所有任务都有很大的共同点:
task copyZipFile() {
doLast {
def remoteBuildProperties = getRemoteBuildProperties(project)
ant {
taskdef(name: 'ftp',
classname: 'org.apache.tools.ant.taskdefs.optional.net.FTP',
classpath: configurations.ftpAntTask.asPath)
ftp(server: remoteBuildProperties['host.name'],
userid: remoteBuildProperties['username'],
password: remoteBuildProperties['password'],
remotedir: 'some-folder', // This value differs from call to call
passive: 'true') {
// The next two lines also are different per case, and might be less or more lines
fileset(dir: rootProject.buildDir) { include(name: 'build.zip') }
fileset(dir: rootProject.projectDir) { include(name: 'build.properties') }
}
}
}
}
我不想重复自己,所以我想将这个代码缩减为一个新的辅助方法来完成这个技巧,以及一个简单的调用方,例如:
task copyZipFile() {
doLast {
def remoteBuildProperties = getRemoteBuildProperties(project)
upload(remoteBuildProperties, 'some-folder') {
fileset(dir: rootProject.buildDir) { include(name: 'build.zip') }
fileset(dir: rootProject.projectDir) { include(name: 'build.properties') }
}
}
}
我将如何实现这一目标?

您可以将内部闭包传递给upload
方法作为最终参数。将委托设置为原始构建器委托,以便正确处理内部闭包调用。例如:
def upload(remoteBuildProperties, folder, body) {
ant {
taskdef(name: 'ftp',
classname: 'org.apache.tools.ant.taskdefs.optional.net.FTP',
classpath: configurations.ftpAntTask.asPath)
ftp(server: remoteBuildProperties['host.name'],
userid: remoteBuildProperties['username'],
password: remoteBuildProperties['password'],
remotedir: folder,
passive: 'true') {
body.delegate = delegate
body()
}
}
}
