在gradle脚本中通过AntBuilder提供main类属性

Question

有没有办法在Groovy的AntBuilder中将jar的清单文件中的主类指定为参数？

def jAnt = project.createAntBuilder();
jAnt.jar(
basedir: build_dir + "/classes", //I have only one class with the main method in it
destfile: build_dir + "/jar/test-jar.jar"
)

我只想在创建jar时在这里指定主类。

所有关于ant任务的文档：https://ant.apache.org/manual/anttaskslist.html

对于jar任务，有很多例子，包括Main-Class规范

您只需要创建相应的groovy构建器代码

def ant = new AntBuilder()
def build_dir = "/11/git/myprj/build"
ant.jar( basedir: "${build_dir}/classes", destfile: "${build_dir}/test-jar.jar"){
manifest{
attribute(name: "Built-By",   value: "me, myself" )
attribute(name: "Main-Class", value: "myPackage.MyClass" )
}
}
