jdk.tools:jdk.tools (or com.sun:tools, or whatever you name it) is a JAR file that is distributed with JDK. Usually you add it to maven projects like this: <dependency>     <groupId>jdk.tools</groupId>     <artifactId>jdk.tools</artifactId>     <scope>system</scope>     <systemPath>${JAVA_HOME}/../lib/tools.jar</systemPath> </dependency> Or, you can manually install tools.jar in the local repository using: mvn install:install-file -DgroupId=jdk.tools -DartifactId=jdk.tools -Dpackaging=jar -Dversion=1.6 -Dfile=tools.jar -DgeneratePom=true and then reference it like Cloudera did, using: <dependency>     <groupId>jdk.tools</groupId>     <artifactId>jdk.tools</artifactId>     <version>1.6</version> </dependency> ...
