[ https://issues.jboss.org/browse/JBIDE-25598?page=com.atlassian.jira.plugi... ] Lukáš Valach commented on JBIDE-25598: -------------------------------------- I installed Oxygen2 and JBT 4.5.2.Final form Eclipse Marketplace, then I disabled all update sites and added only 4.5.3.AM2 staging update site \[1\]. \[1\] http://download.jboss.org/jbosstools/oxygen/staging/updates/ I tried Check For Updates and got this error: {code} Cannot complete the install because of a conflicting dependency. Software being installed: Code Recommenders for Java Developers 2.5.1.v20180130-0943 (org.eclipse.recommenders.rcp.feature.feature.group 2.5.1.v20180130-0943) Software currently installed: Code Recommenders Mylyn Integration 2.5.0.v20171201-1623 (org.eclipse.recommenders.mylyn.rcp.feature.feature.group 2.5.0.v20171201-1623) Only one of the following can be installed at once: Code Recommenders Code‐Completion UI 2.5.0.v20171201-1623 (org.eclipse.recommenders.completion.rcp 2.5.0.v20171201-1623) Code Recommenders Code‐Completion UI 2.5.1.v20180130-0943 (org.eclipse.recommenders.completion.rcp 2.5.1.v20180130-0943) Cannot satisfy dependency: From: Code Recommenders Mylyn Completion UI 2.5.0.v20171201-1623 (org.eclipse.recommenders.mylyn.rcp 2.5.0.v20171201-1623) To: bundle org.eclipse.recommenders.completion.rcp [2.5.0,2.5.1) Cannot satisfy dependency: From: Code Recommenders Mylyn Integration 2.5.0.v20171201-1623 (org.eclipse.recommenders.mylyn.rcp.feature.feature.group 2.5.0.v20171201-1623) To: org.eclipse.recommenders.mylyn.rcp [2.5.0.v20171201-1623] Cannot satisfy dependency: From: Code Recommenders for Java Developers 2.5.1.v20180130-0943 (org.eclipse.recommenders.rcp.feature.feature.group 2.5.1.v20180130-0943) To: org.eclipse.recommenders.completion.rcp [2.5.1.v20180130-0943] {code} Oxygen 2 includes org.eclipse.recommenders.mylyn.rcp 2.5.0 Oxygen 3 includes org.eclipse.recommenders.mylyn.rcp 2.5.1 But our update site don't include o.e.r.mylyn. Maybe you didn't get this problem because you had enabled some additional update sites (e. q. Oxygen update site). I tested also update via Install New Software and got following error: {code} Cannot complete the install because of a conflicting dependency. Software being installed: JavaScript Development Tools 2.1.1.v201711211802 (org.eclipse.wst.jsdt.feature.feature.group 2.1.1.v201711211802) Software currently installed: Eclipse Web Developer Tools 3.9.1.v201711152154 (org.eclipse.wst.web_ui.feature.feature.group 3.9.1.v201711152154) Only one of the following can be installed at once: JavaScript Development Tools 2.1.0.v201706011953 (org.eclipse.wst.jsdt.feature.feature.jar 2.1.0.v201706011953) JavaScript Development Tools 2.1.1.v201711211802 (org.eclipse.wst.jsdt.feature.feature.jar 2.1.1.v201711211802) Cannot satisfy dependency: From: JavaScript Development Tools 2.1.0.v201706011953 (org.eclipse.wst.jsdt.feature.feature.group 2.1.0.v201706011953) To: org.eclipse.wst.jsdt.feature.feature.jar [2.1.0.v201706011953] Cannot satisfy dependency: From: JavaScript Development Tools 2.1.1.v201711211802 (org.eclipse.wst.jsdt.feature.feature.group 2.1.1.v201711211802) To: org.eclipse.wst.jsdt.feature.feature.jar [2.1.1.v201711211802] Cannot satisfy dependency: From: Eclipse Web Developer Tools 3.9.1.v201711152154 (org.eclipse.wst.web_ui.feature.feature.group 3.9.1.v201711152154) To: org.eclipse.wst.jsdt.feature.feature.group [2.1.0.v201706011953] {code} Eclipse offered quite good solution when I choosed "Show original error" and checked "Update" and "Remove". Then it wanted to uninstall o.e.r.mylyn, so I suppose that once you fix mylyn issue, this error dissapears too. -- This message was sent by Atlassian JIRA (v7.5.0#75005)
