Currently CLion 2018.1 RC2 is already available and official release will come later this week.
As a continuation of #175 please extend compatibility to new 181.* versions.
Now on the plugin's page (https://plugins.jetbrains.com/plugin/9554-bazel) only 173.* builds are marked as compatible.
Thanks!
Similarly, IntelliJ IDEA 2018.1 is released and incompatible with Bazel (see last line, in red):

I'm able to use Bazel plugin version 2018.01.02.0.1 with IntelliJ 20181 (181.4203.550) but only if I disable the Go plugin (181.4203.564.171).
If I re-enable the Go plugin the Bazel plugin fails to initialise

Please help to make the plugin compatible with the latest 2018 CLion. Thanks!
We are currently working on the plugin API compatibility fixes required for 2018.1 support. Once that's done, and if there are no major regressions with our internal use case, we'll move to 2018.1.
Any updates on this?
We're working on it. The plugin API used by plugin's supporting non-cmake build systems has changed a lot in 2018.1. We also have to continue supporting pre-2018.1 versions for at least another couple of months. So it will take some time to get all the SDK compatibility code done and properly tested.
2018.1 is now supported, as of the latest plugin upload.
