Re: [che-dev] java development/runtime version
|
Hello, devs.
I've merged restriction as discussed at yesterday's community call.
Hello, devs.
One of the feedback I get is that we might need
to keep backporting code to the java8 based branches for some time.
So it would be nice to restrict usage of new features for some time.
WDYT? Let me know.
Hi Sergii,
Thanks for the update.
Something to keep in mind for anyone who builds Che and Eclipse modules using Eclipse Tycho. Eclipse Tycho does not work properly in a few common circumstances with Maven 3.6.1 and 3.6.2, you need 3.6.3 (the latest release).
HTH,
Jonah
Hello, devs.
che-parent and che prs are merged.
During the update, it turns out that keeping existed mave3.3 version becomes complicated.
We decided to move to 3.6.1 that is explicitly downloaded from Apache servers.
So next time you are going to build che please update your environment to java11 + maven 3.6.x
Salute.
I'm going to start merging PRs with Java 11 migration.
It might bring some period of time when CI may fail.
Sorry for the inconvenience.
Hello, devs.
On yesterday's community call I didn't receive any notifications about blockers that can prevent us from moving forward.
Now we have the first green lights on PRs.
I would like to start merging it next Monday, Jun 15.
Please let me know if you see any problems.
Hello, devs.
We are getting closer to java 11.
I have one additional news.
During testing alpine based image I've noticed quite a few TLS exceptions
that force me to get back to openjdk:11-jre-slim based image
This topic has been discussed yesterday during the community call.
We proposed to wait the release of Che 7 before doing this change as this is not on the critical path of the Che 7 release.
Thanks!
Ok. Make sense. Let's divide this question on two.
1. How to build on Java 11
2. Can we run on Java 11.
I'm more interested in 2. Because if answer - NO, first one doesn't make sense.
I tried building Che w/ OpenJDK 11ea28...
11:10:17 Apache Maven 3.5.4 (1edded0938998edf8bf061f1ceb3cfdeccf443fe; 2018-06-17T18:33:14Z)
11:10:17 Maven home: /var/lib/jenkins/tools/hudson.tasks.Maven_MavenInstallation/maven-3.5.4
11:10:17 Java version: 11, vendor: Oracle Corporation, runtime: /qa/tools/opt/x86_64/openjdk11_ea28
... and it failed spectacularly:
11:21:07 [INFO] Che Core :: Commons :: GWT Logger .................. FAILURE [ 2.758 s]
11:21:07 Caused by: org.apache.maven.plugin.PluginContainerException: An API incompatibility was encountered while executing net.ltgt.gwt.maven:gwt-maven-plugin:1.0-rc-8:package-lib: java.lang.ExceptionInInitializerError: null
Perhaps we need to move to the JDK 11.0.1 and Maven 3.6?
Hello
I would like to initiate discussing around development/runtime version of java that we use to build and run Che. (workspace agent and workspace server).
Idea is to bump version to the latest LTS Java 11 (18.9^ LTS) [1]
Does anybody have any comments or concerns?
