eclipse安装activiti5.18.0工作流插件时遇到的问题

1，首先可以尝试一下在线安装： eclipse中上栏点击：help -> install new software -> add name:Activiti BPMN 2.0 designer Location:http://activiti.org/designer/update/ 如果安装失败，我们就尝试离线安装 2.离线安装 准备工作： 下载activiti的相关版本， 在此附上activiti百度网盘下载地址：https://pan.baidu.com/s/1K7isMRhzWnLaSYk6f1zOlw 提取码：m60i

下载后： eclipse中上栏点击：help -> install new software -> add name:Activiti BPMN 2.0 designer Location： 如果报错这个信息：

Cannot complete the install because one or more required items could not be found.
Software being installed: Activiti Eclipse BPMN 2.0 Designer 5.14.1 (org.activiti.designer.feature.feature.group 5.14.1)
Missing requirement: Activiti Eclipse BPMN 2.0 Designer 5.14.1 (org.activiti.designer.feature.feature.group 5.14.1) requires ‘org.eclipse.emf.transaction 1.4.0’ but it could not be found

解决方案是： 去百度网盘下载，里面有

org.eclipse.emf.transaction_1.4.0.201306111400.jar org.eclipse.emf.validation.ui_1.7.0.201405281429.jar org.eclipse.emf.validation_1.8.0.201405281429.jar org.eclipse.emf.workspace_1.5.1.201306111400.jar

这个4个jar是用处，解决eclipse自身的环境的问题， 地址：https://pan.baidu.com/s/1WgeWUXoF0X94MSvD3M8KRQ 提取码：nnww 将下载下来的jar复制粘贴到elicpse的plugins目录下，重启elicpse， 再次安装，没有报错，静待安装成功即可。

注意：有的大部分的小伙伴应该都可以，但是还有小部分的依旧失败，报错信息为：

An error occurred while collecting items to be installed session context was:(profile=D__DevelopTools_eclipse_jee-oxygen_eclipse, phase=org.eclipse.equinox.internal.p2.engine.phases.Collect, operand=, action=).

No repository found containing: osgi.bundle,oracle.eclipse.tools.rest.lib,17.0.0.201709131633

**解决方案：**

**打开Window->Preferences->Install/Update->Available software Sites,将Oracle Enterprise Pack For Eclipse改为disable**
