Spring 启动：无法打开嵌套条目 'WEB-INF/lib-provided/ecj-3.12.3.jar'

Question

我正在尝试混淆 spring 启动应用程序。套餐：war

我正在使用 yguard 遵循 ant 脚本方法

Link : http://codeaweso.me/2009/02/obfuscating-a-webapp-war-file-with-yguard-and-ant/

项目结构：

main.war

a.jar
b.jar

以及更多第三方依赖项。

我可以看到我们已经成功混淆了所需的第三方依赖项 jar 文件。

此外，我们还保留了其他库的未混淆和未压缩，但有些是如何压缩的。

我们得到的异常是

关于我们可能出现压缩异常的任何建议。

Answer 1

当您尝试构建 jar 时，请仅提供以下选项。

maven-assembly-plugin

 <archive> 
<compress>false</compress>
 </archive>

我们也可以在 spring-boot maven 插件中提供相同的。
