title: Java problems each time I try to import a project to eclipse
body: <p>I have purchased 3 Android games source codes, but when I import any of them to eclipse I get these two errors :</p>
  
  <blockquote>
    <p>The project was not built since its build path is incomplete. Cannot find the class file for java.lang.Object. Fix the build path then try building this project</p>
    
    <p>the type java.lang.object cannot be resolved. it is indirectly referenced from required .class files.</p>
  </blockquote>
  
  <p>When I add the JRE library by clicking right on the project and build path => Configure Build Path => library => add library => JRE System library => Workspace Default jre. I just get more than 400 another error, most are like this : ... cannot be resolved to a type/variable.</p>
  
  <p>Checked for all possible solutions but nothing seems to work for me.</p>
