Java project in Eclipse: The type java.lang.Object cannot be resolved. It is indirectly referenced from required .class files

This is an annoying Eclipse Bug which seems to bite now and then. See http://dev-answers.blogspot.de/2009/06/eclipse-build-errors-javalangobject.html for a possible solution, otherwise try the following;

• Close the project and reopen it.

• Clean the project (It will rebuild the buildpath hence reconfiguring with the JDK libraries)

  OR

• Delete and Re-import the project and if necessary do the above steps again.

The better cure is to try NetBeans instead of Eclipse :-)

The following steps could help:

1. Right-click on project » Properties » Java Build Path
2. Select Libraries tab
3. Find the JRE System Library and remove it
4. Click Add Library... button at right side » Add the JRE System Library (Workspace default JRE)

Here is how I solved it: In Java-ADT: Windows - Preference - Java - Installed JREs Just add another JRE, pointing to the 'jre' folder under your JDK folder. (jre is included in the jdk). Make sure you chose the new jre.
