Reuse an existing build of the JREs rather than building new ones.
In general, copy a justj.manifest link from an existing <a href="https://download.eclipse.org/justj/jres" target="jres">jres/${java.version}/downloads/latest/justj.manifest</a>.
The JDK URLs specified below will be ignored in this case.
<b>To build new JREs, clear this parameter field!<b>
<b>To do a release build, ensure that this field specifies the ${java.version} to be released.<b>
