Cannot make Project Lombok work on Eclipse

Don't forget to do to Project->Clean in eclipse to make sure that your classes are recompiled.

I ran into this problem due to the missing:

-vmargs -javaagent:lombok.jar -Xbootclasspath/a:lombok.jar

as well. What is not explicitly said neither here nor in the Lombok popup message, and was not obvious to me as someone who never before had to fiddle with the eclipse.ini, is that you are NOT supposed to add that line, but instead add the last two parts of that line after the first part, which is already in the eclipse.ini file. To better illustrate, the end of the file should look something like this (bold is what matters for Lombok, the rest might be different for you):

-vm
C:/Program Files/Java/jdk1.7.0_02/bin
-vmargs
-Dosgi.requiredJavaVersion=1.5
-Xms40m
-Xmx384m
-javaagent:lombok.jar
-Xbootclasspath/a:lombok.jar

1. Copy the Lombok jar into your eclipse based IDE (Eclipse/STS etc-) install folder

   • note that the install folder is the folder that has the .ini file for your IDE
   • if you use Maven to pull in the jar, then get it from your m2 repository
   • cp ~/.m2/repository/projectlombork/lombork-1.x.jar /path/to/IDE/lombok.jar

2. Edit the .ini file in the install folder of your IDE and add the following lines below -vmargs.

   • -javaagent:lombok.jar -Xbootclasspath/a:lombok.jar
   • note that the jar should be in the same folder as the .ini file and the name of the jar lombok.jar

3. Restart your IDE and rebuild/maven-update your project

This is for setup of lombok on Spring Tool Suite. Here is what I did on spring tool suite (sts-4.4.0.RELEASE) and lombok-1.18.10.jar (current latest version available in mavenrepository).

1. If having maven project, ensure lombok dependency added to it. Else you need manually add the jar to your project classpath.

   <!-- https://mvnrepository.com/artifact/org.projectlombok/lombok --> <dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> <version>1.18.10</version> <scope>provided</scope> </dependency>

2. Clean build the maven application. This will download lombok jar in your .m2 location by default from maven repository. The path would be org\projectlombok\lombok\1.18.10\

3. Now open command prompt and navigate to the lombok path and execute command java -jar lombok-1.18.10.jar

   C:\xxx\xxx\org\projectlombok\lombok\1.18.10>java -jar lombok-1.18.10.jar

4. Opens up lombok dialog box. If see message Can't find IDE Click Specify location... Provide the path to your STS root location

   My case it is C:\apps\sts-4.4.0.RELEASE\SpringToolSuite.exe

   Install/Update

5. Install successful Click Quit Installer

6. Now in explorer navigate to your STS root path. C:\apps\sts-4.4.0.RELEASE\ We see lombok.jar placed in the sts root path Now edit in notepad SpringToolSuite4.ini file We see following appended at the end

   -javaagent:C:\apps\sts-4.4.0.RELEASE\lombok.jar

7. Start STS using SpringToolSuite4.exe Clean, rebuild your project.

I had similar issue on MacBook Pro, I just followed the below link and issue got resolved. https://projectlombok.org/setup/eclipse

Steps followed:-

• Download the lombok.jar
• Double click on this jar
• This jar will try to find the eclipse installed on the machine, but in my case it was not able to identify the eclipse though I installed on it, this could be due to softlink to the eclipse path.
• I just specified the location of the eclipse ini file by clicking "Specify location" button
• This jar automatically updated the entry in eclipse.ini file for javaagent
  • I added the same jar to the classpath of the project in the eclipse
  • Restarted my eclipse

Eclipse Oxygen - after installation of Lombok according to the process described on the Lombok page, still could not use @Log annotation.

Solution : Project --> Properties - Enable annotation processing

It was little frustrating. But finally it got resolved for me with following solution.

The issue seems to be where "-javaagent:lombok.jar" is placed in your ini file. When i installed it through lombok installation. This line got added towards last parameters after -vmargs. When i moved it up next to -vmargs. the issue got resolved.

I am using windows 10. I followed below steps :

• Added lombok dependency in pom.xml of my project
• Added "-javaagent:{pathOfLombokJarInSystem}" in eclipse.ini file. Path in my case was "-javaagent:C:\Users\ {username} .m2\repository\org\projectlombok\lombok\1.18.6\lombok-1.18.6.jar"
• Started the eclipse and did Maven > Update Project.

This resolved the issue for me.

I am using Eclipse Jee 2019-06 and this worked for me:

• Download Lombok.jar
• Open cmd and run: java -jar Lombok.jar
• Lombok config window will open.
• In “Specify Location” set the path of the eclipse.exe (for example C:\Users\<username>\eclipse\jee-2019-062\eclipse\eclipse.exe )
• Click “Install/Update”
• Quit Installer
• Exit eclipse and Open it again

Done.

For me, The cause is different. My project name in settings.gradle was different from project name in eclipse.

So make sure your eclipse project name is as same as rootProject.name in settings.gradle
