Java gradle java.lang.NoClassDefFoundError

  • 772

我正在使用 Java + Gradle（内置于 intellij idea）（'gradle' = 'sh gradlew'）

在编辑器中或执行时gradle run一切正常，但是当我尝试编译gradle build和运行时，调用时java -jar ./build/libs/LinearServer-1.0-SNAPSHOT.jar出现错误Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/log4j/LoggerLogger.getLogger(Main.class);

build.gradle 文件代码：

plugins {
    id 'java'
    id 'application'
}

group 'ru.screamt5.linear'
version '1.0-SNAPSHOT'

sourceCompatibility = 1.8

mainClassName = 'ru.screamt5.linear.LinearServer.Main'

repositories {
    mavenCentral()
}

dependencies {
    compile group: 'commons-cli', name: 'commons-cli', version: '1.4'
    compile group: 'org.apache.commons', name: 'commons-io', version: '1.3.2'
    compile group: 'com.google.inject', name: 'guice', version: '4.2.0'
    compile group: 'log4j', name: 'log4j', version: '1.2.17'
    testCompile group: 'junit', name: 'junit', version: '4.12'
}


jar {
    manifest {
        attributes(
                'Main-Class': mainClassName,
                'Class-Path': configurations.compile.collect { it.getName() }.join(' ')
        )
    }
}

可能是什么问题呢？

    需要从添加到jar

    jar {
    manifest {
        ...
    }
    from {
        configurations.compile.collect { it.isDirectory() ? it : zipTree(it) }
    }
}
