你能帮我解决这个问题吗。我试着用"Hello，world"这样的简单代码运行scala文件，但出现了类似的错误
C:UsersErsainDocumentsNetBeansProjectsScalaApplication4nbprojectbuild-impl.xml:403: **The following error occurred while executing this line**:
C:UsersErsainDocumentsNetBeansProjectsScalaApplication4nbprojectbuild-impl.xml:236: Problem: **failed to create task or type scalac
Cause: The name is undefined.**
我用这个参数创建了用户变量：SCALA_HOME,值-C:scala-2.9.1-1bin;系统变量具有与用户变量类似的参数
当我转到TOOLS->SCALA PLATFORMS时，它会显示此消息
"Error: The specified folder does not contain a Scala platform.
If you want to specify a different folder for this platform, remove this platform and create a new one with exactly the same name pointing to the correct platform folder."
尝试将SCALA_HOME设置为C:scala-2.9.1-1，而不是bin目录。
