我想使用 ProGuard 混淆和优化 Java JAR 文件。JAR 文件是用于 JDBC 和 SQLite 的自编写类和导入类的集合。
导入的类不必被混淆，但可以优化。拥有一种混淆所有并优化所有配置的配置以及一种仅优化和混淆我的代码并使导入的类保持不变的配置会很好。
我做了一些研究并尝试了不同的配置来实现这一点，但失败了，ProGuard 显示许多警告和几个错误，我尝试更改脚本没有效果或效果很小。
我在 Eclipse 中开发并使用 Antbuild.xml文件来完成这项工作。
有人知道这应该怎么做吗？
这是我的 Ant 构建文件：
<?xml version="1.0" ?>
<project name="Ant-ProGuard-Build" default="main" basedir=".">
