我的解决方案基于使用 Ant( 没有 XML Task )

Using

ant [-Dmanifest.file=<file>] [-Dversion.file=<file>] [-Dbuild.slot=<number>]
    -Dmanifest.file - path and filename AndroidManifest.xml. Default: AndroidManifest.xml in a folder with build.xml
    -Dversion.file - path and file name in which to store the number Build version. Default: version.properties folder with build.xml
    -Dbuild.slot - position of build number in version array. Default: 2, ie X.X.build.

Auto Increment Build in Eclipse

Project | Properties | Builders | New | Ant Build
    Main
        Build file
            <path>/build.xml
        Arguments
            -Dmanifest.file=${workspace_loc://AndroidManifest.xml} -Dversion.file=${workspace_loc://version.properties}
    Refresh
        [x] Refresh resources upon completion
        (*) Specify resources
            [Specify resources] 
                <Project>
                    [x] AndroidManifest.xml
    Build Options
        [x] Specify working set of relevant resources
            [Specify resources] 
                <Project>
                    [x] res
                    [x] src
                    [x] AndroidManifest.xml

我的解决方案使用其他答案( XML Task 和 Groovy ) 中找到的一些代码自动递增构建数字。 我还包括一条规则, 即进行 git 承诺和标记, 将构建数字连接到版本控制中的特定点上, 可用于跟踪错误 。

 <taskdef name="xmltask" classname="com.oopsconsultancy.xmltask.ant.XmlTask"/>


  <path id="groovy.classpath">
    <fileset dir="/Users/deepwinter1/.gvm/groovy/current/lib/">
      <include name="*.jar"/>
    </fileset>
  </path>

  <taskdef name="groovy" classname="org.codehaus.groovy.ant.Groovy">

      buildNum = Integer.valueOf(properties["buildNum"])
      properties["buildNum"] = buildNum + 1
