Project compilation fails in IDEA 14

[mukhanov]

Whole compilation workflow fails when plugin is enabled:

Sigh. It would be nice if JetBrains was better about deprecating API before removing it.

I'm uploading a 0.5.8-EAP release archive that restores function when running under IDEA 14.

[mcamou]

I installed the plugin to get syntax highlighting (we're using Scala and sbt-scalabuf to compile). Even when I disable protobuf compilation in the project settings I get this same error.

[tcripps]

mcamou,

Which version of the plugin did you install? Was it version 0.5.8-EAP (the only version of the plugin that supports IDEA 14)?

[mcamou]

I have the latest one that is available in the IntelliJ repositories (0.5.7). Where do I get 0.5.8-EAP?

[mcamou]

Thanks! That fixed THAT exception. However, in my project I am using scalabuff (called from sbt) to compile the .proto files into Scala (I want to use the plugin just for syntax highlighting). I've gone into Project Structure -> Facets -> Protobuf Facet and disabled the "Enable compilation" checkbox. However, when trying to compile I get the following message:

19:09:59 Throwable: Cannot generate protobuf files as the path to protoc has not been set. Please set in Settins > Compiler 19:09:59 Compilation completed with 0 errors and 0 warnings in 0 sec

Setting the path to protoc in the IntelliJ settings allows me to compile the project, however, I think that should not be necessary since I have disabled compilation.

Please see https://github.com/nnmatveev/idea-plugin-protobuf/issues/48 as well.

Setting the path to protoc in the IntelliJ settings allows me to compile the project, however, I think that should not be necessary since I have disabled compilation. - what did you set it to?

[mcamou]

@GildedHonour You have to install protobuf on your machine (outside of IntelliJ) and then put in the path to the protoc executable

How to compile using http://github.com/nnmatveev/idea-plugin-protobuf ? Is there User-Guide? Demo?

[tcripps]

Read https://github.com/nnmatveev/idea-plugin-protobuf/blob/master/Help.txt. It explains how to install and configure the plugin. Compilation happens "automagically" (once set up) when you build your Java module or project.
