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
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
Restart your IDE and rebuild/maven-update your project

I could not install lombok jar on my MacBook Pro because of the version of Java  I had to downgrade to Java 1 6 to install and then I reused Java 1 7 when the installation worked    You can see the different JVM installed on your machine here    System Library Java JavaVirtualMachines

You not only have to add lombok jar to the libraries  but also install it by either double-clicking the lombok jar  or from the command line run java -jar lombok jar  That will show you a nice installer screen  Select your Eclipse installation and install    Afterwards  you can check if the installer has correctly modified your eclipse ini   -vmargs     -javaagent lombok jar -Xbootclasspath a lombok jar   If your Eclipse was already running  you have to Exit Eclipse and start it again   File Restart is not enough   If you are starting Eclipse using a shortcut  make sure that either there are no command line arguments filled in  or manually add -javaagent lombok jar -Xbootclasspath a lombok jar somewhere after -vmargs   Recent editions of Lombok also add a line to the About Eclipse screen  If Lombok is active you can find a line like  Lombok v0 11 6  Dashing Kakapo  is installed  http   projectlombok org   just above the line of buttons   If for some reason  usually related to customized eclipse builds  you need to use the full path  you can instruct the installer on the command line to do so   java -Dlombok installer fullpath -jar lombok jar

Did you add   -vmargs     -javaagent lombok jar -Xbootclasspath a lombok jar   to your eclipse ini   Because if you have  and if you have added the lombok jar to the libraries used by your project   it works just fine with Eclipse Helios       Ian Tegebo mentions in the comments that      a simple  restart  was not sufficient to pick up the changed vmargs    I needed to explicitly exit and then start again       chrisjleu mentions in the comments      If you happen to be running a customized Eclipse Helios  3 6   distribution then you may have to use the full path to lombok jar in both the vm arguments    See commit b47e87f for more details    boolean fullPathRequired   IdeFinder getOS      EclipseFinder OS UNIX    System getProperty  lombok installer fullpath      null

I searched for lomob jar in  m2 repo  Once you double click it -  Search eclipse exe and select it  After lombok will make the required changes  Explicitly quit eclipse -  it should be fixed by now   If not do a maven Update

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 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

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      If having maven project  ensure lombok dependency added to it  Else you need manually add the jar to your project classpath    lt  -- https   mvnrepository com artifact org projectlombok lombok -- gt   lt dependency gt   lt groupId gt org projectlombok lt  groupId gt   lt artifactId gt lombok lt  artifactId gt   lt version gt 1 18 10 lt  version gt   lt scope gt provided lt  scope gt   lt  dependency gt  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  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 gt java -jar lombok-1 18 10 jar 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 Install successful Click Quit Installer 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 Start STS using SpringToolSuite4 exe Clean  rebuild your project
