在eclipse中为android项目创建jar

Question

大家好我怎样才能创建使用eclipse在android中创建的项目的jar文件.我已经用这种方式完成了项目 - >右键单击 - >导出 - >选择构建器 - > antbuilder - >确定然后在此过程之后将创建build.xml.在bulid.xml上,我将创建新的构建器.

• 右键单击项目 - >属性 - >选择新建 - >给出build.xml和项目路径,然后按"确定",将创建新的构建器.
• 现在从项目属性中选择该构建器,然后按确定.
• 现在构建您的项目,您的jar将在bin文件夹中创建.

我已经按照上面的过程但在bin文件夹中找不到我的jar.我可以看到我的build.xml已创建,所有进程都顺利但仍未创建jar.谁能告诉我怎么能这样做？

我的build.xml

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<!-- WARNING: Eclipse auto-generated file.

              directory with the processing instruction <?eclipse.ant.import?>
              as the first entry and export the buildfile again. -->

在Eclipse中,选择项目,右键单击项目,选择Export,从中选择Jar.然后按照简单向导将目标放在要保存jar的位置,然后完成.你可以在那里找到你的罐子.
