The project was not built since its build path is incomplete

Question

Every time I try to import a project downloaded from googlecode into Eclipse but I get some errors:

The project was not built since its build

Answer 1

I know this is too late. but I am also facing this issue and I fix this by following below steps.

1. This issue is occurred only if the project shared between different machines.
2. For me I found java JDK is the problem.
3. My colleague used mac system and using jdk 1.7. but in my system I used jdk 1.6.
4. I guess that may be the issue. So I select project and open properties and change my jdk to 1.7
5. Change target=Google Inc.:Google APIs:19
6. Clean & Build

Finally issue is fixed. I think this is because of If you build your project with higher JDK version thereafter you should build with same version.

NOTE : we are not facing this issue before until my colleague build with JDK 1.7. After he started to using JDK 1.7 only this issue occur.

Hope it will work for some one. And no need for install new eclipse.
