大家好，我如何创建使用 Eclipse 在 android 中创建的项目的 jar 文件。我已经以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 -> 提供 build.xml 和您的项目路径，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。
我遵循了上述过程，但在 bin 文件夹中找不到我的 jar。我可以看到我的 build.xml 已创建并且所有过程都很顺利，但仍然没有创建 jar。谁能告诉我该怎么做？
我的 build.xml
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
