Java ProGuard例外情况“；输入jar和输出jar必须不同；

我尝试从maven插件运行ProGuard，但发现错误：

[proguard] ProGuard, version 5.2.1
 [proguard] java.io.IOException: Input jars and output jars must be different [D:\projects\demoObfuscation\target\demo-0.0.1-SNAPSHOT.jar].
 [proguard]     at proguard.ConfigurationChecker.checkConflicts(ConfigurationChecker.java:202)
 [proguard]     at proguard.ConfigurationChecker.check(ConfigurationChecker.java:82)
 [proguard]     at proguard.ProGuard.execute(ProGuard.java:73)
 [proguard]     at proguard.ProGuard.main(ProGuard.java:538)

在proGuard配置中，我有：

-injars /target/demo-0.0.1-SNAPSHOT.jar
-outjars /target/demo-pro.jar

编辑：

具有插件的最小POM：

<build>
    <plugins>
      <plugin>
        <groupId>com.github.wvengen</groupId>
        <artifactId>proguard-maven-plugin</artifactId>

com.github.wvengen
proguard maven插件
包裹
前卫
${basedir}/proguard.conf
${java.home}/lib/rt.jar
${java.home}/lib/jce.jar
org.springframework.boot
springbootmaven插件
重新包装
${start class}

我认为您的proguard配置未被读取。尝试直接在插件中配置proguard：

com.github.wvengen

您能提供一个最小的POM吗？@norbjd I eddit问题
-injars/target/demo-0.0.1-SNAPSHOT.jar
应该是
-injars-target/demo-0.0.1-SNAPSHOT.jar
