Question

Gradle在尝试执行grgit任务时抛出NoClassDefFoundError。

build.gradle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。

我是否需要添加groovy作为构建依赖项（错误消息似乎表明）？我将如何以及在何处添加它？

编辑：gradle版本是1.10，如果重要的话。

Answer 1

由于@ user149408指出Gradle版本（v1.10 vs v2.10）不匹配，我进一步挖掘了一下：

gradle-git-plugin commit for v0.7.0指定使用的Gradle版本（v1.11），因此使用v1.10构建的工作正常。

因为Gradle插件总是使用来自Gradle的compile localGroovy()和compile gradleApi()构建，所以如果它使用Gradle 2.x构建，则会导致Groovy不匹配错误。

出了什么问题：任务执行失败'：src：myproject：clone'。   java.lang.NoClassDefFoundError：org / codehaus / groovy / runtime / typehandling / ShortTypeHandling

事实上，Gradle v2.10和gradle-git v1.2.0的组合工作正常。

一些示例build.gradle与问题类似的结构。

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会给你：

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

希望它有所帮助！

Answer 2

我设法解决了它。

grgit-1.2.0似乎依赖于groovy。在classpath / buildscript块中为groovy添加dependencies条目会导致不同的错误：

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

FAILURE: Build failed with an exception.

* Where:
Build file '/home/me/src/myproject/build.gradle' line: 23

* What went wrong:
Execution failed for task ':src:myproject:clone'.
> java.lang.IncompatibleClassChangeError: the number of constructors during runtime and compile time for org.ajoberstar.grgit.auth.AuthConfig$Option do not match. Expected -1 but got 2

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

BUILD FAILED

进一步的研究表明，这可能源于版本不兼容（因为其他原因我坚持使用Gradle 1.10）。

最终我通过回到grgit-0.7.0解决了这个问题。现在我的git任务正常工作，repo被克隆了。
