Ok  if you are using Windows OS   Go to C  Program Files Java jdk1 8 0 40 lib  jdk Version might be different for you  Make sure tools jar is present  otherwise download it  Copy this path  C  Program Files Java jdk1 8 0 40  In pom xml   lt dependency gt   lt groupId gt jdk tools lt  groupId gt   lt artifactId gt jdk tools lt  artifactId gt   lt version gt 1 8 0 40 lt  version gt   lt scope gt system lt  scope gt   lt systemPath gt C  Program Files Java jdk1 8 0 40 lib tools jar lt  systemPath gt   lt  dependency gt   Rebuild and run  BINGO

The problem is in the Eclipse Maven support  the related question is here   Under Eclipse  the java home variable is set to the JRE that was used to start Eclipse  not the build JRE  The default system JRE from C  Program Files doesn t include the JDK so tools jar is not being found   To fix the issue you need to start Eclipse using the JRE from the JDK by adding something like this to eclipse ini  before -vmargs     -vm C   lt your path to jdk170 gt  jre bin server jvm dll   Then refresh the Maven dependencies  Alt-F5   Just refreshing the project isn t sufficient

If you can live without tools jar and it s only included as a chained dependency  you can exclude it from the offending project    lt dependency gt       lt groupId gt org apache ambari lt  groupId gt       lt artifactId gt ambari-metrics-common lt  artifactId gt       lt version gt 2 1 0 0 lt  version gt       lt exclusions gt           lt exclusion gt               lt artifactId gt jdk tools lt  artifactId gt               lt groupId gt jdk tools lt  groupId gt           lt  exclusion gt       lt  exclusions gt   lt  dependency gt

thanks to npe  adding   lt dependency gt       lt groupId gt jdk tools lt  groupId gt       lt artifactId gt jdk tools lt  artifactId gt       lt version gt 1 7 0 05 lt  version gt       lt scope gt system lt  scope gt       lt systemPath gt   JAVA HOME  lib tools jar lt  systemPath gt   lt  dependency gt    to pom xml did the trick

I also faced this problem because I just only installed JRE not with JDK  So   adding dependency for jdk tools can t fix for me because tools jar was not exist at my   JAVA HOME  lib  directory   Now I downloaded and installed JDK  to fix it

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    lt dependency gt       lt groupId gt jdk tools lt  groupId gt       lt artifactId gt jdk tools lt  artifactId gt       lt scope gt system lt  scope gt       lt systemPath gt   java home     lib tools jar lt  systemPath gt   lt  dependency gt    See  the Maven FAQ for adding dependencies to tools jar  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    lt dependency gt       lt groupId gt jdk tools lt  groupId gt       lt artifactId gt jdk tools lt  artifactId gt       lt version gt 1 6 lt  version gt   lt  dependency gt
