Question

我在日食氧气中安装UML Designer 9.0.0时遇到问题，得到错误消息：

Cannot complete the install because one or more required items could not be found.   Software being installed: UML Designer
9.0.0.201901300933 (org.obeonetwork.dsl.uml2.runtime.feature.feature.group
9.0.0.201901300933)   Missing requirement: UML Designer 9.0.0.201901300933 (org.obeonetwork.dsl.uml2.runtime.feature.feature.group
9.0.0.201901300933) requires 'org.obeonetwork.dsl.uml2.core.runtime.feature.feature.group 0.0.0' but it could not be found

似乎需要自行安装，这是毫无意义的

增加了氧气和sirius p2存储库

Answer 1

仔细观察：

org.obeonetwork.dsl.uml2.runtime.feature.feature.group要求
org.obeonetwork.dsl.uml2。核心 .runtime.feature.feature.group

因此DSL UML2 核心功能缺失。我会在UML Designer 9.0.0 or Nightly repository中怀疑它，但是它不存在。在这种情况下，您应该询问存储库的所有者。

在Eclipse Oxygen中安装时，为什么UML Designer自身具有依赖性
