我一直在尝试遵循clouderavm(cdh-5.4.2)的教程,但是在尝试运行构建的jar来计算像素数时遇到了一个异常。
构建本身成功:
[cloudera@quickstart helloWorld]$ gradle jar
:core:compileJava UP-TO-DATE
:core:processResources UP-TO-DATE
:core:classes UP-TO-DATE
:core:jar UP-TO-DATE
:examples:helloWorld:compileJava UP-TO-DATE
:examples:helloWorld:processResources UP-TO-DATE
:examples:helloWorld:classes UP-TO-DATE
:examples:helloWorld:jar
BUILD SUCCESSFUL
Total time: 18.436 secs
This build could be faster, please consider using the Gradle Daemon: https://docs.gradle.org/2.7/userguide/gradle_daemon.html
但是执行jar会引发以下错误:
[cloudera@quickstart helloWorld]$ hadoop jar build/libs/helloWorld.jar examples/sampleNew.hib sampleimages_average

在同一根hipi父项目的示例文件夹中,此子项目的my build.gradle如下所示:
jar {
manifest {
attributes("Main-Class": "org.hipi.examples.HelloWorld")
}
dependencies{
compile project(':core')
}
}
有人能帮我什么我错过了,如何使它运行?
java version "1.8.0_60"
Java(TM) SE Runtime Environment (build 1.8.0_60-b27)
Java HotSpot(TM) 64-Bit Server VM (build 25.60-b23, mixed mode)
由于我是gradle的新手,所以我无法在eclipse下配置hipi以用于其他项目,所以我尝试只运行终端。有人能帮我吗?
注意:我的网络访问受到限制,因此在我的系统中几乎没有下载权限。

我已经解决了这个问题,通过gradle将jar中的所有文件包括在内,如下所示
