用于查找可安装单元的p2 director命令行参数不返回信息

Posted 2021-03-27

我试图使用p2 director和命令行参数从p2存储库中获取可安装单元的列表。我从这篇文章的步骤开始使用-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，命令行什么都不返回。

我的命令行如下所示：

"C:IBMIBM_DevelopmentPackage_for_Eclipse_Win_X86_32_6.5.5eclipseDevelopmentPackageeclipse"eclipsec.exe -application org.eclipse.equinox.p2.director -debug "C:UsersIBM_ADMINDocumentsprojectslocaltpbuildp2Options.txt" -repository 

如您所见，我使用-debug命令打开调试。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中运行命令：

@ECHO OFF
SET _EXEDIR_="C:IBMIBM_DevelopmentPackage_for_Eclipse_Win_X86_32_6.5.5eclipseDevelopmentPackageeclipse"
SET _REPO_=https://download.eclipse.org/technology/swtbot/releases/latest/

@ECHO ON

@ECHO P2 query complete.
@ECHO OFF
pause

结果显示调试信息，但没有条目，是：

我错过了什么吗？

答案

看来你遇到了Eclipse bug 417799。

解决方法是将以下内容添加到命令行（使用...serverjvm.dll而不是...javaw.exe）：

-vm C:IBMIBM_DevelopmentPackage_for_Eclipse_Win_X86_32_6.5.5eclipseDevelopmentPackageibm_sdk80jreinserverjvm.dll
