NoSuchMethodError for DotnetCoreRuntime.getCliExePath

ReSharper Platform
1

I’ve been making use of DotnetCoreRuntime.getCliExePath to determine how to invoke dotnet from my plugin.

var dotNetCoreRuntime = RiderDotNetActiveRuntimeHost.Companion.getInstance(project).getDotNetCoreRuntime().getValue();

if (dotNetCoreRuntime != null && dotNetCoreRuntime.getCliExePath() != null) {
    this.cliExePath = dotNetCoreRuntime.getCliExePath();
}

As of 2026.1.EAP this is failing with java.lang.NoSuchMethodError ‘java.lang.String com.jetbrains.rider.runtime.dotNetCore.DotNetCoreRuntime.getCliExePath()’

Is there a replacement for this method?

Additionally, how can I get my plugin to build/compile against the 2026.1 platform? I’ve tried various versions but none of them work. If I could compile against it I could possibly find a replacement method myself.

platformVersion = 2026.1-SNAPSHOT
platformVersion = 2026.1-EAP5
etc

The method has been replaced by getCliExePath() that returns a Path instead of String.
Unfortunately, this is an incompatible change.

Thanks, I was able to get this working using reflection to call the method and then examining the result to determine what to do with it.
