java - grgit NoClassDefFoundError

Question

尝试执行grgit任务时，Gradle会引发NoClassDefFoundError。
build.gradle的开始:

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.1.2'
        classpath 'org.ajoberstar:gradle-git:1.2.0'
    }
}

apply plugin: 'com.android.application'
//
//

import org.ajoberstar.grgit.*

task clone << {
    File dir = new File('contrib/otherstuff')
    if(!dir.exists()) {
        def grgit = Grgit.clone(dir: dir, uri: 'https://github.com/someguy/otherstuff.git')
    }
    // TODO else (pull)
}


project.afterEvaluate {
    preBuild.dependsOn clone
}

// rest omitted

输出:

Relying on packaging to define the extension of the main artifact has been deprecated and is scheduled to be removed in Gradle 2.0

第20行是对 Grgit.clone()的调用。

我是否需要将groovy添加为构建依赖项(错误消息似乎表明了这一点)？我将如何以及在哪里添加它？

编辑:gradle版本是1.10，如果有关系。

Answer 1

正如@ user149408指出Gradle版本(v1.10与v2.10)不匹配时，我进一步挖掘了一点:

gradle-git-plugin commit for v0.7.0指定使用的Gradle版本(v1.11)，因此使用v1.10的构建可以正常工作。

因为Gradle插件始终使用Gradle的compile localGroovy()和compile gradleApi()构建，所以如果使用Gradle 2.x进行构建，则将引发Groovy不匹配错误。

• What went wrong: Execution failed for task ':src:myproject:clone'. java.lang.NoClassDefFoundError: org/codehaus/groovy/runtime/typehandling/ShortTypeHandling

实际上，Gradle v2.10和gradle-git v1.2.0的组合可以正常工作。

一些示例 build.gradle与问题中的结构类似。

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'org.ajoberstar:gradle-git:1.2.0'
    }
}

import org.ajoberstar.grgit.*

task clone << {
    File dir = new File('contrib/gs-spring-boot')
    if(!dir.exists()) {
        def grgit = Grgit.clone(dir: dir, uri: 'https://github.com/chenrui333/gs-spring-boot.git')
    }
    // TODO else (pull)
}

./gradlew clone将给您:

$ ls contrib/gs-spring-boot/
CONTRIBUTING.adoc   LICENSE.code.txt    LICENSE.writing.txt README.adoc         complete            initial             test
