Answer 1

Ok, if you are using Windows OS

1. Go to C:\Program Files\Java\jdk1.8.0_40\lib (jdk Version might be different for you)

2. Make sure tools.jar is present (otherwise download it)

3. Copy this path "C:\Program Files\Java\jdk1.8.0_40"

4. In pom.xml

   <dependency>
   <groupId>jdk.tools</groupId>
   <artifactId>jdk.tools</artifactId>
   <version>1.8.0_40</version>
   <scope>system</scope>
   <systemPath>C:/Program Files/Java/jdk1.8.0_40/lib/tools.jar</systemPath>
   </dependency>
   

5. Rebuild and run! BINGO!

Answer 2

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:/<your_path_to_jdk170>/jre/bin/server/jvm.dll

Then refresh the Maven dependencies (Alt-F5) (Just refreshing the project isn't sufficient).

Answer 3

Change the set of installed JREs in your eclipse. Window > Preferences > Java > Installed JREs, change the location of jre to %JAVA_HOME%/jre, but not something like C:\Program Files\Java\jre7

Answer 4

If the jdk.tools is present in the .m2 repository. Still you get the error something like this:

missing artifact: jdk.tools.....c:.../jre/..

In the buildpath->configure build path-->Libraries.Just change JRE system library from JRE to JDK.

Answer 5

thanks to npe, adding

<dependency>
    <groupId>jdk.tools</groupId>
    <artifactId>jdk.tools</artifactId>
    <version>1.7.0_05</version>
    <scope>system</scope>
    <systemPath>${JAVA_HOME}/lib/tools.jar</systemPath>
</dependency>

to pom.xml did the trick.

I use below in my MR project.

<exclusions>
                <exclusion>
                    <artifactId>jdk.tools</artifactId>
                    <groupId>jdk.tools</groupId>
                </exclusion>
