I'm trying to import an android project into Eclipse (from Git, but I don't think it's relevant), and I can't run or compile it because I get these errors:

Android requires compiler compliance level 5.0. Please fix project properties.  Serval-Video-Discovery      line 1  Android ADT Problem 
Project 'Serval-Video-Discovery' is missing required source folder: 'gen'   Serval-Video-Discovery      Build path  Build Path Problem

I think the first one isn't really a big problem, even if I don't really understand the warning.

The funny thing is that the "gen" folder exists on the filesystem; furthermore, I can't try to create it because it already exists !

What should I do to solve this issue?

Here is the GitHub repo I'm trying to import from: https://github.com/rbochet/Serval-Video-Discovery

    Just try Restarting eclipse if it doesn't work after trying wat Sandy said. – Niki Mar 16 '11 at 08:59
  • If cleaning the project and restarting Eclipse isn't enough, try removing the `gen` directory from the file system (it's automatically generated, as the name implies). Then run Clean project. This did it for me. – appas Mar 17 '11 at 17:27

Package Explorer -> Right click the project -> "Android Tools" -> "Fix Project Properties"
Project -> Clean

Fixes without having to restart eclipse

Android requires compiler compliance level 5.0. Please fix project properties.

I had the same problem but non of these answers helped me. I found my solution here:

Package Explorer -> Right click the project -> "Android Tools" -> "Fix Project Properties"

  • I used your trick few days ago... I have to say that the "fix the issue button" is always welcome. Good one! – Rob Apr 03 '11 at 07:03
  • Why did I have to search 2 hours only to find the RIGHT MOUSE BUTTON here, Everybody else answering questions, assumed that you know that. But there's beginners too. Txs – Martin Jan 05 '13 at 20:09

I had the same problem but solved in the following way

Package Explorer -> Right click the project -> Properties -> Java Build Path -> Source -> your project name/gen -> click on Remove -> Click on Add Folder -> check gen -> Ok -> Ok

  • "Fix project properties" and "Clean" didn't work. But this worked for me. I had this issue after formatting my computer and re-installing and re-importing my project. Eclipse did not prompt error and ran the last installed program on the phone instead. – Uknight Jul 23 '13 at 10:13

Just right click and delete the gen directory from eclipse. If not, try the fix project properties above.

If gen folder is missing under project after importing an existing project into workplace, just create a gen folder under project and that will fix the above error.
