Question

我尝试通过proguard maven来模糊我的春季启动应用程序。 Proguard成功地混淆了jar文件。但是当我运行obfuscate jar文件时，我收到了这个错误;

java.lang.IllegalStateException: Unable to open nested entry 'lib/spring-boot-starter-data-jpa-1.2.4.RELEASE.jar'. It has been compressed and nested jar files must be stored without compression. Please check the mechanism used to create your executable jar file

这是我的pom.xml;

我忽略了所有第三方依赖项;

               <option>-keep class javax.** { *; }</option>
                <option>-keep class org.** { *; }</option>
                <option>-keep class com.** { *; }</option>
                <option>-keep class commons-io.** { *; }</option>
                <option>-keep class commons-codec.** { *; }</option>
                <option>-keep class ommons-collections.** { *; }</option>
                <option>-keep class commons-dbcp.** { *; }</option>
                <option>-keep class cglib.** { *; }</option>
                <option>-keep class postgresql.** { *; }</option>
                <option>-keep class commons-validator.** { *; }</option>
                <option>-keep class org.springframework.**</option>

但它不起作用。我也尝试使用proguard.conf，但我得到了相同的结果。谢谢你的帮助。

您不需要为正在使用的所有库jar添加-keep选项。只需保留您的Spring Boot应用程序的主要方法，并保留属性和目录结构即可。下面的conf应该可以工作：

# Keeps the directory structure intact.
# Spring's @ComponentScan needs the specified directory structure at runtime as well.
-keepdirectories

-keep public class * { public static void main(java.lang.String[]);}

-keepattributes Exceptions,InnerClasses,Signature,Deprecated,SourceFile,LineNumberTable,*Annotation*,EnclosingMethod
