Error while building project in Netbeans

问题

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:

E:\Backup\My Documents (BackUp)\NetBeansProjects\AccountStatusChanger\nbproject\build-impl.xml:246: Compile failed; see the compiler error output for details.
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,

If you need JDK 7 then you'll have to install it in the second machine.

回答2:

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
