2. Removing “API Baselines error”

After the automatic build, you may see a lot of “red !” and “red X” marks in some of the projects.

Refer to http://stackoverflow.com/questions/13650375/the-red-mark-after-the-build-in-eclipse. For your conveniences in debugging, you need to setup the filter. http://stackoverflow.com/a/13651021/260127

You’ll have “Adding API Baseline in eclipse” error.

You can remove all the errors by making “Missing API baseline” as warning.

3. Removing “Build path specifies execution environment J2SE-1.4” error

You may see “Build path specifies execution environment J2SE-1.4.” error in Mac OS X, it’s because some of the projects use JDK1.4, but the setup in the Mac is wrong.

Check if you have Java SE correctly installed.
