Java build has started failing - Fatal error compiling: java.lang.IllegalAccessError: class lombok.javac.apt.LombokProcessor

Question

We have a Java 11 server on EC2 that has just started failing to build with the following error:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.8.1:compile (default-compile) 
on project showhow-server: Fatal error compiling: java.lang.IllegalAccessError: class lombok.javac.apt.LombokProcessor (in unnamed module @0x49d0e934) cannot access class 
com.sun.tools.javac.processing.JavacProcessingEnvironment (in module jdk.compiler) because module jdk.compiler 
does not export com.sun.tools.javac.processing to unnamed module @0x49d0e934 -> [Help 1]
[ERROR] 

The build is from BitBucket pipelines.

Any idea what it could be?

Answer 1

Upgrade lombok dependency to 1.18.20

Sabotage

With java 11 changing the lombok version from 1.18.16 to 1.18.20 just did the trick for me. Thanks! – Precise

With java 17 for arm64, this solved my error. – Heaviside

With java 17 for arm64, it's working, thanks. – Burgwell

It solved my problem in Java-11 and maven 3.8.1 combination for the lombak. – Kriss

Answer 2

I use java 11 too and fixed the problem by adding this to the POM plugins section.

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>3.8.1</version>
            <configuration>
                <source>${java.version}</source>
                <target>${java.version}</target>
                <fork>true</fork>
                <!-- this is to fix bitbucket pipeline build error due to Lombok processing -->
                <compilerArgs>
                    <arg>-J--add-opens=jdk.compiler/com.sun.tools.javac.code=ALL-UNNAMED</arg>
                    <arg>-J--add-opens=jdk.compiler/com.sun.tools.javac.comp=ALL-UNNAMED</arg>
                    <arg>-J--add-opens=jdk.compiler/com.sun.tools.javac.file=ALL-UNNAMED</arg>
                    <arg>-J--add-opens=jdk.compiler/com.sun.tools.javac.main=ALL-UNNAMED</arg>
                    <arg>-J--add-opens=jdk.compiler/com.sun.tools.javac.model=ALL-UNNAMED</arg>
                    <arg>-J--add-opens=jdk.compiler/com.sun.tools.javac.parser=ALL-UNNAMED</arg>
                    <arg>-J--add-opens=jdk.compiler/com.sun.tools.javac.processing=ALL-UNNAMED</arg>
                    <arg>-J--add-opens=jdk.compiler/com.sun.tools.javac.tree=ALL-UNNAMED</arg>
                    <arg>-J--add-opens=jdk.compiler/com.sun.tools.javac.util=ALL-UNNAMED</arg>
                    <arg>-J--add-opens=jdk.compiler/com.sun.tools.javac.jvm=ALL-UNNAMED</arg>
                </compilerArgs>
                <annotationProcessorPaths>
                    <path>
                        <groupId>org.projectlombok</groupId>
                        <artifactId>lombok</artifactId>
                        <version>${lombok.version}</version>
                    </path>
                </annotationProcessorPaths>
            </configuration>
        </plugin>

The java.verion is 11, lombok.version is 1.18.18

Answer 3

Using maven i managed to build using this (changed source and target to match my java version):

<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.8.1</version>
<configuration>
    <source>16</source>
    <target>16</target>
    <fork>true</fork>
    <compilerArgs>
        <arg>-J--add-opens=jdk.compiler/com.sun.tools.javac.code=ALL-UNNAMED</arg>
        <arg>-J--add-opens=jdk.compiler/com.sun.tools.javac.comp=ALL-UNNAMED</arg>
        <arg>-J--add-opens=jdk.compiler/com.sun.tools.javac.file=ALL-UNNAMED</arg>
        <arg>-J--add-opens=jdk.compiler/com.sun.tools.javac.main=ALL-UNNAMED</arg>
        <arg>-J--add-opens=jdk.compiler/com.sun.tools.javac.model=ALL-UNNAMED</arg>
        <arg>-J--add-opens=jdk.compiler/com.sun.tools.javac.parser=ALL-UNNAMED</arg>
        <arg>-J--add-opens=jdk.compiler/com.sun.tools.javac.processing=ALL-UNNAMED</arg>
        <arg>-J--add-opens=jdk.compiler/com.sun.tools.javac.tree=ALL-UNNAMED</arg>
        <arg>-J--add-opens=jdk.compiler/com.sun.tools.javac.util=ALL-UNNAMED</arg>
        <arg>-J--add-opens=jdk.compiler/com.sun.tools.javac.jvm=ALL-UNNAMED</arg>
    </compilerArgs>
    <annotationProcessorPaths>
        <path>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
            <version>1.18.16</version>
        </path>
    </annotationProcessorPaths>
</configuration>

I inform that this solution worked for me also for v11. Thank you. – Carnelian

Answer 4

when we added below lombok dependency in pom.xml file , it worked for me

<!-- https://mvnrepository.com/artifact/org.projectlombok/lombok -->
<dependency>
    <groupId>org.projectlombok</groupId>
    <artifactId>lombok</artifactId>
    <version>1.18.24</version>
    <scope>provided</scope>
</dependency>

Add below lombok dependency in pom.xml file,

    <dependency>
        <groupId>org.projectlombok</groupId>
        <artifactId>lombok</artifactId>
        <version>1.18.24</version>
        <scope>provided</scope>
    </dependency>

Answer 6

i had faced same issue due to vulnerabilities in current lombok version. please verify vulnerability status of current version and if required, please upgrade it to latest working version.

Genetics

Answer 7

in case anyone runs into this and has to change lots of maven projects to make it work (like me) you can also copy the newer lombok jar into older version's directory and rename it (i.e. lombok-1.18.26.jar to lombok-1.16.18.jar)

this was much easier than changing lombok version in 20+ projects

Answer 8

just check whether you added Lombok dependency, and if you have already then try latest version. for me i am using JDK 22, and Lombok dependency " 1.18.30"
