eclipse安装activiti-designer插件时可能遇到无法安装的问题，提示的错误信息：Cannot complete the install because one or more required items could not be found. Software being installed: Activiti Eclipse BPMN 2.0 Designer 5.18.0 (org.activiti.designer.feature.feature.group 5.18.0) Missing requirement: Activiti Eclipse BPMN 2.0 Designer 5.18.0 (org.activiti.designer.feature.feature.group 5.18.0) requires ‘org.eclipse.emf.transaction 1.4.0‘ but it could not be found 

解决办法：将下载解压后的这三个文件拷贝到eclipse的plugin文件夹下即可解决上述问题 org.eclipse.emf.transaction_1.4.0.v20100331-1738.jar org.eclipse.emf.validation_1.7.0.201306111341.jar org.eclipse.emf.workspace_1.5.1.v20120328-0001.jar
