Junit5: Ask build tools and IDEs to upgrade to junit-platform-launcher 1.6.x

[marcphilipp]

Overview

In #1909 we've improved error reporting for engine discovery/execution failures. The relevant changes are in DefaultLauncher which is contained in the junit-platform-launcher artifact. Since most build tools and IDEs bundle that artifact we need to reach out to them and ask them to update to Jupiter/Vintage 5.6 (Platform 1.6).

Deliverables

IntelliJ doesn't bundle junit-platform-launcher anymore (about a year or even more), it downloads the launcher on tests start according to the version of the api used in the user's project.

[marcphilipp]

@akozlova Thanks for the info! In that case, we're fine where IDEA is concerned.

Eclipse bug report to move to JUnit 5.6: bug 558873.

Surefire issue: https://issues.apache.org/jira/browse/SUREFIRE-1750

[bmuskalla]

Gradle has been upgraded to the 1.6.0 launcher which will be released as part of Gradle 6.4

[marcphilipp]

@bmuskalla Thanks for letting us know! 👍

[sormuras]

Created https://issues.apache.org/jira/browse/SUREFIRE-1764 to update Surefire's dependency.

[Tibor17]

In Surefire we are resolving the version of junit-platform-launcher in runtime. So we only need to fix it and not to upgrade it. Upgrading it would mean either breaking the users or forcing them to upgrade their POMs as well. Pls discuss it.

[sormuras]

In Surefire [...] Pls discuss it.

Let's move the Surefire-related discussion to https://issues.apache.org/jira/browse/SUREFIRE-1764 -- this issue collecting the state of "all" build tools and IDEs.

[marcphilipp]

@sormuras will create tickets for the remaining projects from the issue description.

[sormuras]

Ant is "always up-to-date" as it doesn't bundle any artifact from JUnit 5 -- users are in charge to update their dependencies.

[sormuras]

Netbeans includes JUnit 5.6 since Feb/Mar 2020, i.e. Netbeans 12: https://github.com/apache/netbeans/pull/1977

Seems like @jlink is working on VS Code lately -- is VS Code already on Platform 1.6 or higher, Johannes?

Related issue: https://github.com/microsoft/vscode-java-test/issues/975 "Support other JUnit 5 test engines / support JUnit 5 platform"

[sormuras]

Moved to 5.7 Backlog as not all IDEs/build tools are on JUnit Platform 1.6, resp. Jupiter 5.6.

[jlink]

@sormuras All I did is to enable VS Code to run other engine tests from an editor.

Under the hood VS Code is using some Eclipse-related library to start JUnit 5 tests in a very hacky way (i.e. through a faulty command line). It basically works with no engine correctly, with Jupiter it does the simple things right.

I offered to support them when migrating to use junit-platform-launcher. As of today they have not taken me up on my offer.

Closing since all build tools and IDEs on the list have been contacted.
