任何解决此问题的线索或指针，并使用oomph成功设置eclipse开发环境？

Answer 1

从日志中，您正在尝试安装org.eclipse.help.infocenter_feature.feature.group，此功能需要org.apache.commons.el。

您能说出您在安装程序中选择了什么吗？

这是您编写的设置任务吗？ 如果是这样，您可能需要一个P2设置任务，其中包含提供此捆绑包的P2 Repo。

重现您的问题：

步骤1：为Eclipse Commiter选择任何Eclipse＆＃34; Eclipse IDE＆＃34;是一种可能性：

第2步：选择项目的设置＆＃34; UA＆＃34; （UA在＆＃34;平台＆＃34;：

下表示user assistance）

此项目的安装脚本存在问题。目前，＆＃34; UA＆＃34;在Bug 497350解决之前，无法使用Oomph设置项目。
