I just tried to send a Maven-based project to another computer and HORROR, red markers everywhere!!
However, mvn clean install is building just fine.
Quickly, I noticed that Lombok is not generating getters and setters for my classes, although the @Getter and @Setter are being correctly recognised by Eclipse.
Both computers use the same Maven version (3.0.4) but different JDKs (1.6_23 and 1.6_33). They both use Eclipse Indigo 32 bit. Do you have an idea about how to solve the problem?
Download Lombok Jar, let’s maven do the download on our behalf :
<dependency>
<groupId>org.projectlombok</groupId>
<artifactId>lombok</artifactId>
<version>1.16.18</version>
</dependency>
Now... mvn clean install command on the newly created project to get this jar downloaded in local repository. Goto the jar location, execute the command prompt, run the command : java -jar lombok-1.16.18.jar
click on the “Specify Location” button and locate the eclipse.exe path
LIKE :
finally install this by clicking the “Install/Update”
If you are using maven and Eclipse, must be installed manually.
<dependency>
<groupId>org.projectlombok</groupId>
<artifactId>lombok</artifactId>
<version>1.18.10</version>
<type>jar</type>
</dependency>
If you use STS. You must have Lombok installed in your Eclipse by running lombok-abc.jar
Please Following the Steps:
-Include pom in Maven .
-Exit/Shutdown STS(must)
-Find lombok Jar in ~.m2\repository\org\projectlombok\lombok\1.18.12
-From Command
After then
After then select the STS.exe
After then click to update/update
then Quit Installer
Happy Coding
Blockquote
just adding the dependency of Lombok is not enough. You'll have to install the plugin of Lombok too.
You can get your Lombok jar file in by navigating through (Only if you have added the dependency in any of the POM.)
m2\repository\org\projectlombok\lombok\1.18.12\lombok-1.18.12
Also, if Lombok could not find the IDE, manually specify the .exe of your IDE and click install.
Restart your IDE.
That's it.
If you face any problem,
Below is a beautiful and short video about how to install the plugin of Lombok.
Just to save your time, you can start from 1:40.

If it still doesn't work,
Verify that lombok.jar is there in your sts.ini file (sts config file, present in sts folder.)
-javaagent:lombok.jar
Do an Alt+F5. This will update your maven.
Close your IDE and again start it.
For Sprint STS - Place the lombok.jar file in the eclipse/sts exe folder and add the following entry to the STS.ini.
-javaagent:lombok.jar
Solution for Eclipse IDE:
1. Maven dependency in pom.xml
<dependency>
<groupId>org.projectlombok</groupId>
<artifactId>lombok</artifactId>
<optional>true</optional>
</dependency>
2. Go to Maven dependency jar >> Right click >> Run As >> Java Application
3. select Socket Server and Click OK
ch.qos.logback.classic.net.SimpleSSLSocketServer
ch.qos.logback.classic.net.SimpleSocketServer
4. Show message on console like:
Wrong number of arguments. Usage: java ch.qos.logback.classic.net.SimpleSocketServer port configFile
I spent full day, you can do it this way:
When using lombok on a fresh installation of Eclipse or STS, you have to:
Install the lombok jar which you can get at https://projectlombok.org/download. Run the jar (as Administrator if using windows) and specify the path to your Eclipse/STS installation.
Restart your IDE (Eclipse or STS)
Give some time for eclipse to generate the class files for lombok (Might take a up to 4 mins in some cases)
Download Lombok Jar File https://projectlombok.org/downloads/lombok.jar
Add maven dependency:
<dependency>
<groupId>org.projectlombok</groupId>
<artifactId>lombok</artifactId>
<version>1.16.18</version>
</dependency>
Start Lombok Installation java -jar lombok-1.16.18.jar
find complete example in this link:
https://howtodoinjava.com/automation/lombok-eclipse-installation-examples/
I am using Red hat Jboss developer studio. I solved this issue by:
The project has lombok dependency. First look into your .m2
repository and find the lombok jar
Double click on the jar, you will see installer there specify the path for IDE like C:\Users\xxx\devstudio\studio\devstudio.exe
Restart the IDE and update the maven project the error will go
1) Run the command java -jar lombok-1.16.10.jar. This needs to be run from the directory of your lombok.jar file.
2) Add the location manually by selecting the eclipse.ini file(Installed eclipse directory). Through “Specify location”
Note : Don't add the eclipse.exe because it will make the eclipse editor corrupt.
I also encountered this issue, for my case, it's because I upgrade my IntelliJ IDEA without upgrading the Lombok plugin. So they are incompatible.
What I had to do was to install lombok in the eclipse installation directory.
Download the lombok.jar from here and then install it using the following command:
java -jar lombok.jar
After that make sure that the lombok.jar is added in your build path. But make sure you don't add it twice by adding once through maven or gradle and once again in eclipse path.
After that clean and build the project again and see all the errors go away.
Intellij User, make sure you have 3 things,
<dependency>
<groupId>org.projectlombok</groupId>
<artifactId>lombok</artifactId>
<version>1.18.8</version>
<scope>provided</scope>
</dependency>
IntelliJ plugin for Lombok
Lombok annotation, like @Getter @Setter (make sure it is coming from lombok and not from somewhere else)
and it should work.
In mac os lombok will not be able to find eclipse location. please click on specify location and go to the eclipse installed folder you can find the eclipse.ini file select that
Seem the answers above are OK in some cases but my case not work well somehow.
So, here what I did (that worked for me):
https://projectlombok.org/p2, the version is 1.18.22SpringToolSuite4.ini, this line: -javaagent:D:\xxx\eclipse\sts-4.13.0.RELEASE\plugins\org.projectlombok.agent_1.18.22/lombok.jarALT+F5 (to open your maven projects), click OK and wait all projects to be builtAnd they are working.
Discussion
It might be above all solutions are working but can because of the version as we always thought, we need to use the same version as in our pom.xml but it could also work with the latest one (correct me if anyone have comment).
Point 2. maven projects, I did since beginning with other above solutions but still got error; somehow we have to make sure that.
One more remark: whenever you don't see a line of message in About Spring Tool (or About Eclipse), meant that your lombok installation not correct, may try my above solution again.
Hope this discussion helps others.
There are already many answer to this question. I'll add to the already given answer.
For Spring STS, if after following the correct way and installing and you get install successful and still it is not working. Please follow below steps.
Open .ini file. and update the javaagent value like this. Also make sure you have lombok.jar in the same folder.
-javaagent:lombok.jar
Now restart the STS and then right click on the project.
Maven -> Update Project
Check force Update of snapshot/releases.
click on OK.
It will take some time and it will resolve all lombok errors.
Remove @Getter from private static field.
If you are using maven , Go to maven dependencies in your project structure then run lombok jar as java project it will install it then exit and start eclipse
