我是黑莓开发的初学者（java）。我有C / C ++，Qt / QML的经验，但没有Java技能。我已成功使用模拟器和设备上的其他示例。 但是，我从Github下载了代码并导入到带有JDK 6.0和7.0的Blackberry Eclipse插件（版本1.5.0）。它无法在模拟器或设备上运行并出现错误：

如何解决这个案子？感谢。
的问候， QC

确保已将Java / bin文件夹设置为PATH系统环境变量。
警告不是问题的原因。线上描述的问题：
Error: Cannot run program "jar": CreateProcess error=2, ?????????
这意味着BlackBerry编译器没有找到标准的java编译器（javac.exe）来继续编译过程。
通过将系统PATH变量设置为JavaSDK / bin文件夹，确保可以从任何地方访问javac.exe所在的文件夹。
例如，如果您已将标准Java SDK安装到文件夹C:\Java，则将以下字符串添加到系统PATH变量中：
C:\Java\bin
