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

Question

I have following dependency in pom.xml:

    org.projectlombok
    lombok

        

Answer 1

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 2

I encountered this issue when upgrading my project from JDK 8 to JDK 12 and using gradle instead of maven and using the io.franzbecker:gradle-lombok gradle plugin to configure lombok automatically.

In this scenario changing buildScript.dependencies from classpath "io.franzbecker:gradle-lombok:1.14" to classpath "io.franzbecker:gradle-lombok:3.2.0" did the trick for me.

Answer 3

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.

Answer 4

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 5

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 6

Solved this by:

1) download the lombok-edge.jar,

2) using following dependency:

<dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
            <version>1.16.21</version>
            <scope>system</scope>
            <systemPath>/Users/xxx/Downloads/lombok-edge.jar</systemPath>
        </dependency>
