lombok.javac.apt.LombokProcessor could not be initialized

Question

my question somewhat relates to this post: Gradle build fails on Lombok annotated classes I am using jhipster and lombok 1.16.18 with a build.gradle as follows

...
apply plugin: 'net.ltgt.apt'
...
dependencies {
    provided "org.projectlombok:lombok:${lombok_version}"
    apt "org.projectlombok:lombok:${lombok_version}"
}
...

but get the following error during compileJava:

warning: lombok.javac.apt.LombokProcessor could not be initialized. 
Lombok will not run during this compilation: 
java.lang.IllegalArgumentException: com.sun.tools.javac.api.ClientCodeWrapper$WrappedStandardJavaFileManager extends com.sun.tools.javac.api.ClientCodeWrapper$WrappedJavaFileManager implements javax.tools.StandardJavaFileManager

What am I missing here?

Answer 1

if you are using gradle this has worked for me

dependencies {    annotationProcessor group: 'org.projectlombok', name: 'lombok', version: '1.18.16'}

Answer 2

I was facing the similar warning in my project as we moved from JDK 8 to JDK 9.

Upgrading the lombok version helped me with removing the error.

        <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
            <version>1.16.20</version>
            <scope>provided</scope>
        </dependency>

I found the reference over here https://github.com/rzwitserloot/lombok/issues/1541

Answer 3

Output of gradlew -v shows that you are using JDK 9 which is not supported by JHipster 4.10.2, please use JDK 8. Same for Lombok.
