Lombok IntelliJ IDEA Plugin: Use of var is disabled by default
I'm using the Lombok Plugin for IntelliJ IDEA . When try to run Java code using the var keyword, I get the following error:
Use of var is disabled by default. Please add 'lombok.var.flagUsage = ALLOW' to 'lombok.config' if you want to enable is.
How do you do that in IntelliJ IDEA ? I created the lombok.config in the project root and pasted lombok.var.flagUsage = ALLOW but it didn't fix it. val is working but not var . I can't seem to find clear instructions on enabling var .
My Lombok maven dependency is:
<dependency>
<groupId>org.projectlombok</groupId>
<artifactId>lombok</artifactId>
<version>1.16.18</version>
<scope>provided</scope>
</dependency>
You may need to recompile everything in order to observe the effect.
Actually, any change of any lombok.config anywhere should trigger a recompilation of all classes in the subtree. This is not the case as such changes are rare and don't warrant the probably non-trivial amount of work.
