我有一个带有多个scala spark程序的项目，而我通过eclipse运行mvn install我能够获得正确的jar生成，它与spark-submit命令一起运行。
在将代码推送到GIT后，我们尝试使用jenkins构建它，因为我们希望使用ansible自动将jar文件推送到我们的hadoop集群。 我们将构建目标的jenkinsfile称为“compile package install -X”。

我在类似帖子中看到了错误 -
Maven: No primary artifact to install, installing attached artifacts instead
但在这里答案说 - 删除自动清理，我不知道如何在jenkins构建jar文件时停止它。
下面是pom.xml -

我尝试指定
1 - 用于在pom.xml中打包的“jar”。
2 - 将maven目标改为 -
“安装”
“干净安装”
“编译包安装”
但是上面的尝试并没有帮助摆脱这个消息，而创建的jar也毫无用处。
当我尝试执行spark submit命令时 -
spark-submit --driver-java-options -Djava.io.tmpdir=/home/EH2524/tmp --conf spark.local.dir=/home/EH2524/tmp --driver-memory 2G --executor-memory 2G --total-executor-cores 1 --num-executors 10 --executor-cores 10 --class com.esi.spark.storedprocedure.Test_jdbc_nospark --master yarn /home/EH2524/PROJECT1-0.0.1-20171124.213717-1-jar-with-dependencies.jar
Multiple versions of Spark are installed but SPARK_MAJOR_VERSION is not set
Spark1 will be picked by default

这里，Test_jdbc_nospark是一个scala对象。
答案 0 :(得分：0)
我不确定，但您的maven-jar-plugin配置看起来很可疑。通常，执行将指定阶段，如
<execution>
<phase>package</phase>
<goals>
<goal>jar</goal>
</goals>
（来自this example）。也许省略这会导致你的默认jar不被构建？当然，错误消息听起来像你的默认jar没有被构建，但你实际上并没有这样说。
答案 1 :(得分：0)
此消息是因为maven-jar-plugin具有as true。一旦我删除了这个，构建就不会给出消息＆＃34;没有要安装的主要工件，而是安装附加工件＆＃34;
由于pom.xml中的路径不正确而导致空jar被创建
Intitally -
<build>
<sourceDirectory>src/main/scala</sourceDirectory>
当jenkins在git中构建代码时，pom就在项目文件夹中。
<build>
<sourceDirectory>folder_name_in_git/src/main/scala</sourceDirectory>
