【问题描述】：
我正在尝试使用带有命令行参数的 p2 director 从 p2 存储库中获取可安装单元的列表。我从这篇文章中的步骤开始使用 -list 参数：
Command line to find units in a p2 repository using p2 query language
但是，当我运行 p2 director 时，命令行什么也没有返回。
我的命令行如下所示：
"C:\IBM\IBM_DevelopmentPackage_for_Eclipse_Win_X86_32_6.5.5\eclipseDevelopmentPackage\eclipse"\eclipsec.exe -application org.eclipse.equinox.p2.director -debug "C:\Users\IBM_ADMIN\Documents\projects\localtpbuild\p2Options.txt" -repository
如您所见，我使用 -debug 命令打开了调试。我的选项文件包含：
org.eclipse.equinox.p2.core/debug=true
org.eclipse.equinox.p2.core/artifacts/mirrors=true
我正在从批处理文件运行命令：
@ECHO OFF
SET _EXEDIR_="C:\IBM\IBM_DevelopmentPackage_for_Eclipse_Win_X86_32_6.5.5\eclipseDevelopmentPackage\eclipse"
SET _REPO_=https://download.eclipse.org/technology/swtbot/releases/latest/

@ECHO ON

@ECHO P2 query complete.
@ECHO OFF
pause
显示调试信息但没有条目的结果是：

Press any key to continue . . .
我错过了什么吗？
