Trying to autogenerate pojos during compile time in sbt

[nnbbz]

Hello, thank you providing the sbt plugin for the codegen! I just had a question. Currently, I have to run sbt graphqlCodegen (to autogenerate the pojos) and then run sbt compile to compile the code.

What I want to do is trigger graphqlCodegen automatically when I run sbt compile. I've been trying to get this working in my build.sbt but with no luck (perhaps my syntax is not correct?)

I have the following line in my build.sbt, but it complains that graphqlCodegen is not defined. Can you shed some light on how I can do this?

(compile in Compile) := ((compile in Compile) dependsOn graphqlCodegen).value

I'm new to SBT

@nnbbz
Please use (compile in Compile) := ((compile in Compile) dependsOn (graphqlCodegen in GraphQLCodegenConfig)).value

In SBT plugins, there is a concept of scope to distinguish between multi module and multi project. So you have to specify the task in which scope.

Because the generated code will be changed which should be known to users. (Although I'm a Scala developer, I'm not sure it's appropriate, so I didn't do that for the plugin).

If you think it's necessary to build an issue to track it, I'll consider implementing it.

Thank you, that worked!

Unfortunately, when I do sbt run, it looks like it invokes sbt compile whenever sources change. Which will now invoke the plugin and I get this exception:

Caused by: java.lang.Exception: Unable to delete directory
at io.github.dreamylost.graphql.codegen.GraphQLCodegenPlugin.$anonfun$projectSettings$14(GraphQLCodegenPlugin.scala:225)

Is there anyway for the plugin to not delete the directory and instead just delete/replace the files. Or make that an option? I understand why you would want to delete the directory (to remove old autogenerated classes)

@jxnu-liguobin
Are you modifying the code while the play app is running and then reloading（will compile） it automatically
Yes I'm actually doing this. When I run the app and make modifications to the code, it will automatically compile. This generally leads to an exception where it fails to delete the directory and after that, it will not recover unless I restart sbt.

@nnbbz Do you use idea SBT shell or stand-alone SBT? What is the version?

[jxnu-liguobin]

I exec sbt run with idea or terminal or sbt shell but it didn't reappear.
Are we missing some key information? Could you provide your build.sbt？

1. By idea
   

2. By terminal
   

3. By sbt shell

@jxnu-liguobin Are you on windows? It might be a windows issue? I had a friend try it as well, and he wasn't getting this issue either.

@nnbbz No,
