通过编程方式从防暴螺栓中删除拓扑时发生编译错误:具有相同名称的对象和程序包 [英] Compile Error when killing topology from storm bolt programatically: object and package with same name

问题描述

我一直在寻找如何从我的Scala项目中的风暴1.2.1中的风暴螺栓中杀死拓扑的方法. 在此 answer 中，我编写了以下代码来做到这一点:

I was looking for how to kill a topology from a storm bolt in storm 1.2.1 in my scala project. From this answer, I wrote following code to do it:

  private def shutTopology(){
    import org.apache.storm.utils.Utils
    import org.apache.storm.utils.NimbusClient
    val conf = Utils.readStormConfig
    val nimbusClient = 
NimbusClient.getConfiguredClient(conf).getClient
    nimbusClient.deactivate(topology_name)
  }

但是它在行中给出了以下错误:val conf = Utils.readStormConfig，该如何解决?

But it given following error in line: val conf = Utils.readStormConfig, How to resolve this?

错误:(46，17)软件包守护程序包含对象和具有相同名称的软件包:nimbus

Error:(46, 17) package daemon contains object and package with same name: nimbus

其中之一需要从类路径中删除

one of them needs to be removed from classpath

val conf = Utils.readStormConfig

val conf = Utils.readStormConfig

通过同时通过sbt和mvn进行编译，我克服了错误.我在此处看到了一些说明，但在如何操作方面没有太多帮助解决这个问题.

I get above error by compiling via both sbt and mvn. I see some description for this here but not much help on how to resolve this.

基于答案此处，我能够使用以下scalac选项在sbt中对其进行编译:

Based on the answer here, I was able to compile this in sbt using following scalac options:

"-Yresolve-term-conflict:object"

使用Maven进行编译时，我仍然无法解决该错误.

I am stil not able to get this done how to resolve this error when compiling with maven.

推荐答案

基于答案此处，我能够使用以下scalac选项在sbt中对此进行编译:

Based on the answer here, I was able to compile this in sbt using following scalac options:

"-Yresolve-term-conflict:object"

要使用Maven进行编译，我按照建议的此处在pom.xml中进行了以下更改:

to get this compiled with maven, I did following changes in my pom.xml as suggested here:

<configuration>
      <scalaVersion>${scala.version}</scalaVersion>
      <args>
        <arg>-Yresolve-term-conflict:object</arg> //this was added
      </args>
      <jvmArgs>
        <jvmArg>-Xms2048m</jvmArg>
        <jvmArg>-Xmx4096m</jvmArg>
      </jvmArgs>
</configuration>
