Maven: JAVA_HOME/lib/tools.jar as dependency

Question

Im new to Maven. I must use class sun.security.tools.JarSigner in my project.Im trying add tools.jar as dependency.I proceeded by Maven's FAQ, other articles from stackowerflow and google but without some positive results.

My NetBean can "see" JarSigner class wit pom beloow.

I can compile project without error or warn but I cant run it.

pom.xml:

Can you please specify your JAVA_HOME variable's value ? – Shmulik Klein Aug 22 '15 at 18:50 — Shmulik Klein, Aug 22 '15 at 18:50

Change <systemPath>${java.home}/../lib/tools.jar</systemPath> to <systemPath>${java.home}/lib/tools.jar</systemPath>.

By the way, are you aware you are making a separation by the JDK version ? the default-tools.jar profile will be activated for jdk 1.6 and below (according to the java.vendor property) and since I see you are using jdk 7, I guess this is redundant.

I defined `/opt/jdk1.7.0_67` and use `${java.home}/lib/tools.jar` steel same result. – Krakonos Aug 23 '15 at 09:28
I would have try to remove the section and put 1.7.0_67 to see what happens. – Shmulik Klein Aug 23 '15 at 12:05

My solution: I extract package sun.security.tools from tools.jar and this compiled sources copy to src folder. At compile phase I copy compiled classes into target.

      <plugins>
          <plugin>
              <artifactId>maven-resources-plugin</artifactId>
              <version>2.7</version>
              <executions>
                  <execution>
                      <id>copy-resources</id>
                      <phase>compile</phase>
                      <goals>
                          <goal>copy-resources</goal>
                      </goals>
                      <configuration>
                          <outputDirectory>${basedir}/target/classes/sun/security/tools</outputDirectory>
                          <resources>          
                              <resource>
                                  <filtering>false</filtering>
                                  <directory>${basedir}/src/main/java/sun/security/tools/</directory>
                                  <includes>
                                      <include>*.class</include>
                                  </includes>
                              </resource>
                          </resources>              
                      </configuration>            
                  </execution>
              </executions>
          </plugin>
