Tycho 编译器插件无法生成 lombok 函数

Question

We have an OSGI framework and we are introducing Lombok in it. In the pom.xml we added the dependency

<dependency>
    <groupId>org.projectlombok</groupId>
    <artifactId>lombok</artifactId>
    <version>1.18.22</version>
</dependency>

but mvn install compilation still fail with

org.eclipse.tycho:tycho-compiler-plugin:2.0.0:compile (default-compile) on project XXX: Compilation failure: Compilation failure: [ERROR] ... [ERROR] ... [ERROR] The method setXXX(String) is undefined for the type XXX

From Eclipse, everything compile and is working fine. lombok.jar was also added to Bundle-ClassPath of MANIFEST.MF We added the annotationProcessorPaths to the pom.xml without success

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>3.8.1</version>
    <configuration>
        <source>1.8</source>
        <target>1.8</target>
        <annotationProcessorPaths>
            <path>
                <groupId>org.projectlombok</groupId>
                <artifactId>lombok</artifactId>
                <version>1.18.22</version>
            </path>
        </annotationProcessorPaths>
    </configuration>
</plugin>

EDIT Even when configuring tycho compiler it doesn't work

        <plugin>
            <groupId>org.eclipse.tycho</groupId>
            <artifactId>tycho-compiler-plugin</artifactId>
            <version>${tycho-version}</version>
            <configuration>
                <source>${compileSource}</source>
                <target>${compileSource}</target>
                <compilerArguments>
                    <processor> lombok.launch.AnnotationProcessorHider$AnnotationProcessor
                    </processor>
                </compilerArguments>
            </configuration>
        </plugin>

when I added set MAVEN_OPTS="-javaagent:C:\\Eclipse\\lombok.jar" compilation worked, so is there any way to add this argument inside the compiler configuration in the pom.xml with a generic path to the lombok.jar

Answer 1

I'm succeeded in using Lombok within a eclipse plugin, and building the plugin with tycho. https://github.com/poul-m/tycho-lombokizer

Answer 2

when I added set MAVEN_OPTS="-javaagent:C:\Eclipse\lombok.jar" compilation worked, so is there any way to add this argument inside the compiler configuration in the pom.xml with a generic path to the lombok.jar

I was able to create .mvn/jvm.config in my project directory and configure a path relative to the project directory in there. Maven Tycho then successfully build my project with Lombok annotations:

This would be the content of the jvm.config:

-javaagent:project/relative/path/to/lombok.jar

https://maven.apache.org/configure.html

Edit: I only tried it with Maven Tycho 2.7.0
