Where the first error type is for the fields in this class:

package com.mangusbrother.akka.calculator.lib.operation.multiply;


import com.mangusbrother.akka.calculator.lib.operation.MathematicalResult;
import lombok.Data;

/**
 * Created by Mangusbrother on 14/02/2016.
 */
@Data
public class MultiplyResult implements MathematicalResult 
 private static final long serialVersionUID = 738641818941986L;
 private final int firstNumber;
 private final int secondNumber;
 private final int result;

and the second error is when a class tries to access getters from lombok classes

My maven pom.xml has the following in it:

<properties>
 <lombok.version>1.16.6</lombok.version>
</properties>
<dependencies>
 <dependency>
 <groupId>org.projectlombok</groupId>
 <artifactId>lombok</artifactId>
 <version>$lombok.version</version>
 </dependency>
</dependencies>
<build>
 <plugins>
 <plugin>
 <groupId>org.apache.maven.plugins</groupId>
 <artifactId>maven-compiler-plugin</artifactId>
 <version>2.3.2</version>
 <configuration>
 <source>1.8</source>
 <target>1.8</target>
 </configuration>
 </plugin>
 </plugins>
</build>

I don't know why but you got compiler error because of maven-compiler-plugin. If you can please change plugin version to 3.5 and check if it will work.

<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>$maven-compiler-plugin.version</version>
<configuration>
 <annotationProcessorPaths>
 **<path>
 <groupId>org.projectlombok</groupId>
 <artifactId>lombok</artifactId>
 <version>$lombok.version</version>
 </path>**
 </annotationProcessorPaths>
</configuration>

I struggled mightily with this and concluded that Lombok 1.16+ and Java 8 are a problem with earlier versions of Maven's compiler plugin. IDEA 2017.1 was building the code without errors, but Maven was throwing 'symbol not found' errors on public methods that were definitely there in a decompiled jar file.

By upgrading to maven-compiler-plugin 3.6.1 across my project and its libraries I was able to get it resolved without having to go down the Delombok path, which I really wanted to avoid.

You will also need to check what version of java is there in path . My issue was with Java 1.8 & 3.5 version . To get it working I had to switch to 1.7 & 3.5 . Please note we are still on 1.7

First you should locate your lombok source (java annotated with lombok) into src/main/lombok and add the lombok-maven-plugin to your project like this:

<build>
 <plugins>
 <plugin>
 <groupId>org.projectlombok</groupId>
 <artifactId>lombok-maven-plugin</artifactId>
 <version>1.16.6.1</version>
 <executions>
 <execution>
 <phase>generate-sources</phase>
 <goals>
 <goal>delombok</goal>
 </goals>
 </execution>
 </executions>
 </plugin>
 </plugins>
</build>

If you don't like to use the lombok-maven-plugin you need to add the following:

<dependencies>
 <dependency>
 <groupId>org.projectlombok</groupId>
 <artifactId>lombok</artifactId>
 <version>1.16.6</version>
 <scope>provided</scope>
 </dependency>
</dependencies>

If you really like to put your lomboked source into src/main/java instead of the default /src/main/lombok you have to go this way which is not recommended:

<build>
 <sourceDirectory>target/generated-sources/delombok</sourceDirectory>
 <testSourceDirectory>target/generated-test-sources/delombok</testSourceDirectory>
 <plugin>
 <groupId>org.projectlombok</groupId>
 <artifactId>lombok-maven-plugin</artifactId>
 <version>1.16.6.1</version>
 <executions>
 <execution>
 <id>delombok</id>
 <phase>generate-sources</phase>
 <goals>
 <goal>delombok</goal>
 </goals>
 <configuration>
 <addOutputDirectory>false</addOutputDirectory>
 <sourceDirectory>src/main/java</sourceDirectory>
 </configuration>
 </execution>
 <execution>
 <id>test-delombok</id>
 <phase>generate-test-sources</phase>
 <goals>
 <goal>testDelombok</goal>
 </goals>
 <configuration>
 <addOutputDirectory>false</addOutputDirectory>
 <sourceDirectory>src/test/java</sourceDirectory>
 </configuration>
 </execution>
 </executions>
 </plugin>
</build>
