Question

我正在将项目源从一台PC转移到另一台。当我点击Netbeans的Clean and Build Main Project菜单中的Run时，我收到了此错误：

init:
deps-clean:
Updating property file: E:\Backup\My Documents (BackUp)\NetBeansProjects\AccountStatusChanger\build\built-clean.properties
Deleting directory E:\Backup\My Documents (BackUp)\NetBeansProjects\AccountStatusChanger\build

BUILD FAILED (total time: 0 seconds)

我该怎么办？我需要重新安装SDK吗？

Answer 1

看起来好像原始机器安装了JDK 7并且项目已配置为目标，但第二台机器有旧版本。

您可以将项目配置为目标1.6或1.5，

或

如果您需要JDK 7，那么您必须在第二台机器上安装它。

Answer 2

正如@ madth3所说，问题在于项目构建目标版本。您导入的源是JDK 7平台的目标。您可以在系统上安装JDK 7，也可以将项目构建目标更改为JDK 1.6。

更改目标平台：

右键单击项目节点，选择属性
在属性窗口的“来源”下，将“源/二进制格式”更改为所需平台
