Java.lang.illegalaccesserror: class lombok.javac.apt.LombokProcessor cannot access class com.sun.tools.javac.processing.JavacProcessingEnvironment
Quick-fix the IllegalAccessError
by aligning Lombok release with your JDK:
If the problem is stubborn like a mule, switch your JDK to meet Lombok's prerequisites:
Ensuring JDK and Lombok handshake
Ensure a friendly handshake between the JDK version and Lombok release. A mismatch might be as undesirable as socks with sandals. JDK 16 needs a companion of Lombok 1.18.22 or higher. Be aware of potential module access restrictions due to modularization in Java 9 and later.
Maven's dance with JDK 16
For Maven users, teach the maven-compiler-plugin
to dance with JDK 16 by --enable-preview
and stating source/target compatibility:
Friendly Annotation Processor Paths
Embrace Lombok tightly into annotationProcessorPaths
to ensure it doesn't suffer from an identity crisis during compilation in newer JDK versions:
Compiler flags charm for unwanted module access restriction
Sometimes, you may have to impress JDK with some compiler flags (--add-opens
) to gain access for Lombok to JDK's members-only club:
More flesh to the tale: JDK Encoding and Compiler Options
Get more verbose feedback! Set UTF-8
encoding and ask for ShowDeprecation
and ShowWarnings
bulletins in the Maven compiler plugin:
Lombok alternatives for incompatible companions
If Lombok and your Java version just don't get along like cats and dogs, it's time to consider manual interventions of Lombok-like features. @Getter
, @Setter
annotations could be your friends, or switch to newer kids on the block: data classes in Kotlin or record types in Java!
Seeking support in Cyberspace
Stuck with incompatibility issues? Time to surf the wave and learn from online tutorials or blogs on implementing features provided by Lombok. Collective wisdom is powerful!
