[ https://issues.jboss.org/browse/JBIDE-25894?page=com.atlassian.jira.plugi... ] Mickael Istria commented on JBIDE-25894: ---------------------------------------- To workaround the issue with JDT versions, I used the following command which seems to properly install everything at one (from Eclipse Platform zip, nightly build {quote} $ ./eclipse -nosplash -consoleLog -application org.eclipse.equinox.p2.director -repository http://download.eclipse.org/jdtls/snapshots/repository/latest/ -repository http://download.eclipse.org/eclipse/updates/4.8-I-builds/I20180402-2000/ -repository http://download.eclipse.org/releases/photon -repository http://download.jboss.org/jbosstools/oxygen/development/updates/ -installIU org.eclipse.jdt.ls.core/0.0.0 -installIU org.jboss.tools.ws.jaxrs.feature.feature.group/0.0.0 -installIU org.jboss.tools.cdi.feature.feature.group/0.0.0 -installIU org.jboss.tools.maven.hibernate.feature.feature.group/0.0.0 -installIU org.hibernate.eclipse.feature.feature.group/0.0.0 -installIU org.eclipse.m2e.wtp.jaxrs.feature.feature.group/0.0.0 {quote} I couldn't see Jax-RS contributing completion or warning because the Jax-RS plugin requires UI Harness to startup, and UI Harness is not available in JDT-LS. So for Jax-RS, it would require to first split the bundle into a UI and a non-UI part. I tried to get CDI reporting something, but I didn't manage to get CDI error markers even from JBoss Tools... So if anyone has an example project showing CDI warnings, please share it so I can test. [~fbricon] maybe? -- This message was sent by Atlassian JIRA (v7.5.0#75005)
