Caused by: java.lang.ClassNotFoundException: com.sun.tools.javac.code.TypeTags when using lombok

Question

I have following dependency in pom.xml:

<dependency>
    <groupId>org.projectlombok</groupId>
    <artifactId>lombok</artifactId>
    <version>1.16.8</version>
</dependency>

When I run mvn clean install, I have following error:

Caused by: java.lang.ClassNotFoundException: com.sun.tools.javac.code.TypeTags
    at java.lang.ClassLoader.findClass (ClassLoader.java:711)
    at java.lang.ClassLoader.loadClass (ClassLoader.java:566)
    at lombok.launch.ShadowClassLoader.loadClass (ShadowClassLoader.java:418)

I tried to use java 1.8, 1.9, 1.10. And I tried lombok 1.6.10, 1.6.12, 1.6.20. All of them have the same problem.

Answer 1

I am able to solve the problem in my maven project with Java-10 and Lombok 1.18.2.

<dependency>
    <groupId>org.projectlombok</groupId>
    <artifactId>lombok</artifactId>
    <version>1.18.2</version>
    <scope>provided</scope>
</dependency>

Answer 2

I had changed the lombok version and it worked for me.

        <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
            <version>1.16.22</version>
            <scope>provided</scope>
        </dependency>

Answer 3

I have the same problem and I solve it by adding this code in pom.xml

<dependency>
    <groupId>org.projectlombok</groupId>
    <artifactId>lombok-maven-plugin</artifactId>
    <version>1.18.0.0</version>
</dependency>

Answer 4

Solved the issue by upgrading lombok version from 1.16.18 to 1.16.22 . I suspect any compatible version higher than .22 might do the trick.
