Maven how to skip test to save build time

I was build Clojure 1.6 from the source and don't need to run the tests. By default, Maven ... the tests are right. It will be waste of time to run the test again. It may take quite a lot of time ... (default-testResources) @ clojure --- [INFO] Not copying test resources [INFO] [INFO] --- maven-compiler ... [INFO] [INFO] --- maven-surefire-plugin:2.6:test (default-test) @ clojure --- [INFO] Tests

Maven build goals how to select

I got a Maven project, but the source code shows errors, even if it was built successfully before and never changes later, all the error are about missing jars.

So I try to build it again with Maven
