grgit NoClassDefFoundError

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
:src:myproject:clone FAILED

FAILURE: Build failed with an exception.

* Where:
Build file '/home/me/src/myproject/build.gradle' line: 20

* What went wrong:

* Try:

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（错误消息似乎表明了这一点）？我应该如何以及在哪里添加它？

编辑：gradle 版本是 1.10，如果重要的话。

Answer 1

我已经解决了。

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

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

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）。

最终我回到 grgit-0.7.0 解决了这个问题。现在，我的 git 任务开始运行并且存储库已被克隆。

Answer 2

正如@user149408 指出的 Gradle 版本（v1.10 vs v2.10）不匹配，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 的构建工作正常。

因为 Gradle 插件总是使用来自 Gradle 的 compile localGroovy() 和 compile gradleApi() 构建，那么如果它使用 Gradle 2.x，它会导致 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

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

一些样本 build.gradle 与问题中的结构相似。

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 会给你：

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