I am transferring a project source from one pc to another. When I click Clean and Build Main Project from Run Menu of Netbeans, I got this error:
init:

BUILD FAILED (total time: 0 seconds)
what will I do? Do i need to reinstall the SDK?
回答1:
It looks as if the original machine has JDK 7 installed and the project was configured with that as the target, but the second machine has an older version.
- You can configure the project to target 1.6 or 1.5,
or
- If you need JDK 7 then you'll have to install it in the second machine.

As @madth3 said, the problem is with the project build target version. The source you have imported is target for JDK 7 platform. Either you install JDK 7 on you system or change the project build target to JDK 1.6.
To change the target platform:
- Right click on the project node, select properties,
- Under "sources" in the properties window, change "source/binary format" to the desired platform
