Strange issue starting maven site (problems occurred while processing POM)
I am trying to run the mvn site but every time I get this error message. I tried googling but didn't find any solutions. I am on a windows machine running maven from git bash.
[WARNING] Unable to create Maven project for org.crashub: crash.shell: pom: 1.3.1 from repository. org.apache.maven.project.InvalidProjectModelException: Some problems were encountered while processing the POMs: [ERROR] 'dependencies.dependency.systemPath' for com.sun: tools: jar must specify an absolute path but is /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home/../Classes/classes .jar @ line 98, column 19

I found these 2 related problems:
https://jira.exoplatform.org/browse/CRASH-225
https://jira.codehaus.org/browse/MSHADE-185
So the reason seems to be in the Maven Shade Plugin: CRaSH POM seems to use the Shade plugin and then has the wrong hard-coded systemPath.
According to http://www.crashub.org/ :
CRaSH is officially built as Spring Boot Remote Shell.
So, org.crashub: crash.shell: pom: 1.3.1 seems to be related to Spring Boot, but I don't know what is meant by the warning: "Unable to create Maven project for [...]"
EDIT
Try adding the following dependency to your POM:
<dependency>
<groupId>com.sun</groupId>
<artifactId>tools</artifactId>
<version>1.8</version>
<scope>system</scope>
<systemPath>${java.home}/../lib/tools.jar</systemPath>
<optional>true</optional>
</dependency>
