I cloned a project from github, the projects made using java 8, spring boot, mysql,

so the first thing I did was configuring the jdk in intellij, I have openjdk 17 , and 15 , so I chose v15 , I run the application,

it's running fine, and when I tried to make mvn package this error came out:

Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.8.1:testCompile (default-testCompile) on project platform: Fatal error compiling: java.lang.IllegalAccessError: class lombok.javac.apt.LombokProcessor (in unnamed module @0x16a9eb2e) 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 @0x16a9eb2e

This is the pom.xml file:

I tried to check the Maven version in my machine , and it's 3.8.5, so I don't know if the problem is because the project's Maven compiler is 3.8.1 and mine is 3.8.5, I'm a newbie so I really dont have a solution for this , I'm just trying to containerize this application that's why I'm building the jar file.

  • As you probably want to compile for Java 8 instead of 15 or 17, you could try to add ``, `` as well as `` properties for Java 8. If this still does not work you need to open the respective modules to the unnamed module. This can either be done by adding that option to the respective plugin, i.e. [like this](https://stackoverflow.com/questions/64920521/how-to-pass-add-opens-jdk-module-configuration-to-maven-test) or via a [.mvn/jvm.config file](https://nipafx.dev/maven-on-java-9/#applying-java-9-flags-to-maven-process) – Roman Vottner Feb 19 '23 at 02:19
  • If this project used lombok you have to correctly configure lombok ... there is a documentation how to do that correctly... also your spring boot version is out of date... – khmarbaise Feb 19 '23 at 11:10

in your pom.xml , properties, add these:

    <properties>
        <java.version>1.8</java.version>
        <!-- START ADD 20230219 -->
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <maven.compiler.source>1.8</maven.compiler.source>
    <maven.compiler.target>1.8</maven.compiler.target>
    <!-- END ADD 20230219 -->
    </properties>

in dependency org.projectlombok , add version

        <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
            <version>1.18.20</version>
            <optional>true</optional>
        </dependency>

I already test OK, in command line or in IDEA IDE.

Other answer maybe can OK in command line , but fail in IDEA IDE.

like this: can OK in command line , but fail in IDEA IDE.

I am test, not good answer in IDEA IDE.
