我有一个项目，有大约100个顶级包。我希望能够为这些顶级软件包制作一个jar。下面的代码可以找到顶级包，但是如何实际执行排除操作以便只得到一个？
最好将其概括为这样，这样就可以处理不在顶级的包。

sourceSets {
    List<String> folders=new LinkedList<>()
    String target="r"
    for(String path:main.java.srcDirs) 
        for(String name:new File(path).list())
            if(!name.equals(target))
                if(new File(path,name).isDirectory()) 
                    folders.add(name)
    println("how to exclude these folders: "+folders)

}

在空目录中，可以使用以下脚本创建源设置的模拟：

def dir = new File('src/main/java')

['a', 'b', 'c', 'd', 'e'].each { l1 -> 
  ['x', 'y', 'z', 'r', 'v'].each { l2 -> 
    def f = new File(dir, "$l1/$l2/SampleClass.java")
    f.parentFile.mkdirs()
    f.text = """\
      package ${l1}.${l2};

      class SampleClass { 

      }
    """.stripIndent()
  }
}

运行时，生成以下内容：

─➤ groovy write.groovy 

─➤ find src/main/java -type f | sort
src/main/java/a/r/SampleClass.java
src/main/java/a/v/SampleClass.java
src/main/java/a/x/SampleClass.java
src/main/java/a/y/SampleClass.java
src/main/java/a/z/SampleClass.java
src/main/java/b/r/SampleClass.java
src/main/java/b/v/SampleClass.java
src/main/java/b/x/SampleClass.java
src/main/java/b/y/SampleClass.java
src/main/java/b/z/SampleClass.java
src/main/java/c/r/SampleClass.java
src/main/java/c/v/SampleClass.java
src/main/java/c/x/SampleClass.java
src/main/java/c/y/SampleClass.java
src/main/java/c/z/SampleClass.java
src/main/java/d/r/SampleClass.java
src/main/java/d/v/SampleClass.java
src/main/java/d/x/SampleClass.java
src/main/java/d/y/SampleClass.java
src/main/java/d/z/SampleClass.java
src/main/java/e/r/SampleClass.java
src/main/java/e/v/SampleClass.java
src/main/java/e/x/SampleClass.java
src/main/java/e/y/SampleClass.java
src/main/java/e/z/SampleClass.java

以下是 build.gradle 在此目录树的根目录中：

apply plugin: 'java'

task jara(type: Jar) {
  archiveBaseName = 'jara'
  from jar.source
  include 'a/**/*'
}

task jarb(type: Jar) {
  archiveBaseName = 'jarb'
  from jar.source
  include 'b/**/*'
}

artifacts {
  archives jara, jarb
}

然后可以运行：

─➤ gradle clean build 

BUILD SUCCESSFUL in 509ms

产生：

─➤ ls -1 build/libs
groovy-how-to-programmatically-exclude-top-level-packages-from-src-java-in-gradle.jar
jara.jar
jarb.jar

i、 e.两个jar文件，其中一个包含 a 顶级包，其中包含 b 顶级套餐。
不确定这是否符合你的目标，但它应该给你一些如何实现你想要的想法。
