java - 无法打开 .jar 中的嵌套条目

Question

我有与 spring boot loader 一起运行的 .jar:

apply plugin: 'spring-boot'

jar {
    into('lib') {
        from configurations.runtime
    }
    manifest {
        attributes("Implementation-Vendor": "tttt",
            "Implementation-Title": project.name,
            "Implementation-Version": version,
            "Implementation-Vendor-Id": "tttt",
            "Built-By": "Administrator",
            "Build-Jdk": "1.7.0_101",
            "Start-Class": "org.cp.Application",
            "Spring-Boot-Version": "1.3.3.RELEASE",
            "Main-Class": "org.springframework.boot.loader.JarLauncher")
    }
}

我运行我的构建:

:ttt:compileJava
:ttt:processResources
:ttt:classes
:ttt:findMainClass
:ttt:jar
:ttt:bootRepackage
:ttt:assemble
:ttt:check
:ttt:build

java -jar tttt.jar:

java.lang.IllegalStateException: Unable to open nested entry 'lib/spring-boot-starter-1.3.3.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

at org.springframework.boot.loader.Launcher.launch(Launcher.java:60)
at org.springframework.boot.loader.JarLauncher.main(JarLauncher.java:52)

如果这意味着什么，我手动将 spring.boot.loader 展开到 src/main/resources 中。我在这里做错了什么？

您不能在 JAR 中执行 Jar。如果你需要这样做，那么你必须将依赖的 JAR 添加到环境变量并使用它。
