Issue
I am trying to build a maven-scala project. After creating the project, I created "clean compile" to build the project. When I run the build option, I see the below exception message:
"C:\Program Files\Java\jdk1.8.0_151\bin\java.exe" -Dmaven.multiModuleProjectDirectory=C:\ABCSparkWorkSpace\DataExpo "-Dmaven.home=C:\Program Files\JetBrains\IntelliJ IDEA Community Edition 2018.1.4\plugins\maven\lib\maven3" "-Dclassworlds.conf=C:\Program Files\JetBrains\IntelliJ IDEA Community Edition 2018.1.4\plugins\maven\lib\maven3\bin\m2.conf" "-javaagent:C:\Program Files\JetBrains\IntelliJ IDEA Community Edition 2018.1.4\lib\idea_rt.jar=54199:C:\Program Files\JetBrains\IntelliJ IDEA Community Edition 2018.1.4\bin" -Dfile.encoding=UTF-8 -classpath "C:\Program Files\JetBrains\IntelliJ IDEA Community Edition 2018.1.4\plugins\maven\lib\maven3\boot\plexus-classworlds-2.5.2.jar" org.codehaus.classworlds.Launcher -Didea.version=2018.1.4 clean compile

I downloaded the scala plugin from online on IntelliJ. My Java version is: "1.8.0_151". Below are the contents of my pom.xml file:

Could anyone let me know what is the problem here and how can I fix it ?
Solution
You're using a deprecated version of the plugin. try to replace every
<groupId>org.scala-tools</groupId>
<artifactId>maven-scala-plugin</artifactId>
by
<groupId>net.alchim31.maven</groupId>
<artifactId>scala-maven-plugin</artifactId>
<version>3.4.0</version>
and remove (the repo no longer exists)
<repositories>
<repository>
<id>scala-tools.org</id>
<name>Scala-Tools Maven2 Repository</name>
<url>http://scala-tools.org/repo-releases</url>
</repository>
</repositories>
<pluginRepositories>
<pluginRepository>
<id>scala-tools.org</id>
<name>Scala-Tools Maven2 Repository</name>
<url>http://scala-tools.org/repo-releases</url>
</pluginRepository>
</pluginRepositories>
and use a more recent version of scala like 2.11 or 2.12
I guess you used a 8 years old template.
