    <p>
      Classpath variables can be used in a Java Build Path to avoid a reference to the local file system. Using a variable entry, the classpath only contains a variable and the
      build path can be shared in a team. The value of the variable has to be configured on this page.

      Certain class path variables are set internally and can not be changed in the Classpath variables preferences:

    <ul>

        JRE_SRC: The source archive for the currently used JRE.
