p2 director 命令行参数查找可安装单元没有return信息

Question

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。我从这个 post 开始使用 -list 参数的步骤：

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returns什么都没有。

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

我正在运行从批处理文件中执行命令：

@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 Querying P2...
@ECHO ON
%_EXEDIR_%\eclipsec.exe -application org.eclipse.equinox.p2.director -debug "C:\Users\IBM_ADMIN\Documents\projects\localtpbuild\p2Options.txt" -repository %_REPO_% -list
@ECHO P2 query complete.
@ECHO OFF
pause

显示调试信息但没有条目的结果是：

P2 query complete.
Press any key to continue . . .

我是不是漏掉了什么？

看来你运行变成了Eclipse bug 417799。

作为解决方法，将以下内容添加到您的命令行（使用 ...\server\jvm.dll 而不是 ...\javaw.exe）：

-vm C:\IBM\IBM_DevelopmentPackage_for_Eclipse_Win_X86_32_6.5.5\eclipseDevelopmentPackage\ibm_sdk80\jre\bin\server\jvm.dll
