Error in eclipse

Hello all, I import flink/gelly in Eclispe 4.4.2. But in the test code, the IDE always prompt TestExecutionMode cannot be resolved to a type. I find TestExecutionMode is a enum type in org.apache.flink.test.util. Apart from this, the other parts works well, there is no error in the main code.
