Notes to zelf

• Red exclamation mark - project won’t build - would not say why. Renamed the mains to main1 still no joy. Finally went to Build Path > Order and Export and ticked export on the JRE

      <?xml version="1.0" encoding="UTF-8"?>
      <classpath>
         <classpathentry excluding="gr/uoa/di/mde515/engine/HeapFile.java" kind="src" path="src"/>
     -   <classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER/org.eclipse.jdt.internal.debug.ui.launcher.StandardVMType/JavaSE-1.7"/>
     +   <classpathentry exported="true" kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER/org.eclipse.jdt.internal.debug.ui.launcher.StandardVMType/JavaSE-1.7"/>
         <classpathentry kind="output" path="bin"/>
      </classpath>
  

  Lo and behold -> red ! became red x.
  Maybe a bug in caching ? (noted this after the Stack Overflows). I then unticked the JRE and still builds ok. See. Clean did not work and I had no missing libs either.

• Server update sites:

    <?xml version="1.0" encoding="UTF-8"?>
    <bookmarks>
       <site url="http://download.jboss.org/jbosstools/updates/development/luna/" selected="true" name="_jboss_tools"/>
       <site url="http://download.oracle.com/otn_software/oepe/luna/" selected="true" name="_oracle_glassfish"/>
    </bookmarks>
  

  Unneeded are the maven ones (m2e-wtp had some uninstalled items though) :

    <site url="http://download.eclipse.org/m2e-wtp/milestones/luna/1.1.0" selected="true" name="_m2e-wtp"/>
    <site url="http://download.eclipse.org/technology/m2e/releases" selected="true" name="_m2eclipse"/>
  

• Clean eclipse OSGi cache: Add -clean to eclipse.ini - first line, on its own - cleans mainly folder {eclipse}\configuration\org.eclipse.osgi. See How to run eclipse in clean mode? and what happens if we do so?. For workspace leaning see Clean out Eclipse workspace metadata - apparently -clean cleans the workspace too (?)

• How to make xml file always be opened in text editor rather than xml editor
