为什么 UML Designer 在 Eclipse Oxygen 中安装时依赖于自身

Question

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

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

似乎需要自己安装，毫无意义

添加了氧气和天狼星P2存储库

Answer 1

仔细观察：

• org.obeonetwork.dsl.uml2.runtime.feature.feature.group 需要
• org.obeonetwork.dsl.uml2.core.runtime.feature.feature.group

因此，DSL UML2 Core功能缺失。我会怀疑它在UML Designer 9.0.0或Nightly存储库中，但它不存在。在这种情况下，您应该询问存储库的所有者。
