[MikitaY]

Description:

Fixes #561 (#561)

Updated the Rider plugin to be compatible with JetBrains Rider 2026.1 by addressing breaking changes in the SDK and build tooling.

Changes made:

• Updated JetBrains.Rider.SDK to 2026.1.0.1
• Updated Gradle wrapper to 9.4.1
• Updated intellij-platform Gradle plugin to 2.5.0
• Updated Kotlin to 2.1.10
• Fixed SubmenuBehavior usage — constructor became private, replaced with SubmenuBehavior.Custom()
• Removed [NotNull]/[CanBeNull] annotations from JetBrains.Annotations which became inaccessible in the new SDK
• Fixed deprecated toLowerCase() → lowercase() in protocol/build.gradle.kts
• Fixed project.exec {} → providers.exec {} for Gradle 9 compatibility
• Fixed Rider dependency declaration: rider(version) { useInstaller = false }
• Fixed platform type from "riderRD" to "RD"

Tested on:

• Rider 2026.1
• .NET Framework 4.7.2

This is generated with AI, right? This doesn't work and you change a lots of things that is not needed... Also, I already fix this on the pull request #559 and is only a constructor that is removed on 2026.1

[MikitaY]

Oh, no, maybe only the text of the PR was generated by AI, I updated the SDK Rider and the rest of the packages that were required. I've probably done some extra work😅 but it helped me run the plugin. Thank you for your work

[MikitaY]

I looked at my PR again, I did an unnecessary refactoring (I like to remove warnings) and Rider my moved the lines automatically, for that I bring my changes, I can fix that if the rest of the changes are needed. I didn't have the plugin build when replacing the constructor, that's the first thing I did

[MikitaY]

@Zarpyk Have you tried building your version? It doesn't work for me, I tried your version

[Zarpyk]

Yes, it build successfully and I use it on my job, you need java 21 to build it. I've tried compiling your version and it don't have the option to format.

[MikitaY]

Thanks, I will install the right version of java and try again. Strange, I and my coworkers have a version running exactly the one assembled and attached to the comment above in zip. I also use it in my work. In any case, a 2 line change is better than a 100 line change 😁

[MikitaY]

I checked your branch again, it is built, but uses rider sdk 2025.1, yes, the plugin is built and works on Rider 2026.1, the documentation states that you need a intelliJPlatform version of at least 2.13 to work with sdk 2026.1 version

intelliJPlatform

RIDER: May need updating with new Rider releases

so I think your update is not enough

Look at what packages it downloads when it builds a plugin or runs it for debugging, for me it’s Rider 2025.1. You have a great simple hack, but I think that this is not a full update for the new Rider release
