ProGuard JNI错误 [英] ProGuard JNI Error
问题描述
我正在使用 ProGuard
来模糊我的Java桌面应用程序.当我启动模糊的JAR
时,出现以下错误:
I'm using ProGuard
to obfuscate my Java Desktop application. When I launch the obfuscated JAR
, I'm getting the following error:
> java -jar program.jar
Error: A JNI error has occurred, please check your installation and try again
Exception in thread "main" java.lang.VerifyError: Expecting a stackmap frame at branch target 80

我在我的项目中使用以下 Maven
依赖项:
I'm using the following Maven
dependencies in my project:
<dependencies>
<dependency>
<groupId>commons-io</groupId>
<artifactId>commons-io</artifactId>
<version>LATEST</version>
</dependency>

</dependency>
</dependencies>
我的ProGuard配置文件也如下所示:
Also my ProGuard configuration file looks as follows:
-microedition
-dontskipnonpubliclibraryclassmembers
-keepdirectories
-target 1.8
-forceprocessing
-dontoptimize
-allowaccessmodification
-overloadaggressively
-keeppackagenames org.**
-dontpreverify
-verbose
-dontwarn **.**
-keep class org.sqlite.** {
<fields>;
<methods>;
}
-keep class com.sun.** {
<fields>;
<methods>;
}
-keep class com.google.** {
<fields>;
<methods>;
}
-keep class oshi.** {
<fields>;
<methods>;
}
# Rest omitted
我尝试禁用优化,预验证,缩小,混淆以及还删除了-target 1.8
标志.只有这样,错误才会消失.
I tried disabling optimization, preverification, shrinking, obfuscation and also removing the -target 1.8
flag. Only then the error go away.
但是我想保留所有选项,并且不要破坏输出JAR
,否则毫无意义.我该怎么办?
But I would like to keep all options and not break the output JAR
otherwise it's pointless. How do I do that?
推荐答案
您正在构建桌面应用程序,因此需要禁用以下选项:
You are building a Desktop application, thus you need to disable the following option:
-microedition
此外,Java 7+版需要进行预验证,因此您还需要禁用:
Additionally, preverification is needed for Java versions 7+, thus you also need to disable:
-dontpreverify
-target 1.8
也可以省略.
