Error during maven build in Scala-Spark - eclipse

Question

I am trying to create simple spark application using Eclipse and Maven. I am getting following error while maven build
Failed to execute goal net.alchim31.maven:scala-maven-plugin:3.2.0:compile (default) on project XXXX: wrap: org.apache.commons.exec.ExecuteException: Process exited with an error: 1 (Exit value: 1) -> [Help 1]
I am using following POM.xml for maven build

Answer 1

Please refer this link
<execution>
<id>scala-compile-first</id>
<phase>process-resources</phase>
<goals>
<goal>add-source</goal>
<goal>compile</goal>
</goals>
</execution>
<execution>
<id>scala-test-compile</id>
<phase>process-test-resources</phase>
<goals>
<goal>testCompile</goal>
</goals>
</execution>
we have to add process-resources phase first then next process-test-resources
then only scala-maven-plugin is able to identify classpath resources properly.

contains excellent way to start coding in Apache Spark. It specify a remote archetype which I added it in maven catalog. And now I am using it to implement spark application.

Shutdown zinc first. See the documentation here
./build/zinc-<version>/bin/zinc -shutdown
