I added lombok
to my java project in eclipse
. It required me to add the last two lines in eclipse.ini
file as vmargs
.
-showlocation
-vm
/home/$USER/JavaSE8/jdk1.8/bin/java

-javaagent:/home/$USER/eclipse/4.4-luna-SR2/lombok.jar
-Xbootclasspath/a:/home/$USER/eclipse/4.4-luna-SR2/lombok.jar
I have also added lombok.jar
in libraries
(Project -> Properties -> Libraries) and also moved lombok.jar
to the topmost level in Order and Export tab (Project -> Properties -> Order and Export) in eclipse and JRE System Library (rt.jar, resources.jar, etc.) all are below lombok.jar
. I'm confused about the order in which lombok
main class will be loaded as :
When eclipse
is launched, the Bootstrap
classloader should load all JDK classes in directory of JRE. (But since I have moved lombok.jar
up in Order and Export, above JRE system libraries, will rt.jar be loaded after lombok.jar
. Mostly No? because bootstrap libraries should always be loaded first no matter WHAT !)
Since we also redefined the bootstrap classpath
using -XBootstrapClasspath option, lombok.jar will be loaded by Bootstrap Classloader
.
After that Extensions classloader
loads the classes in lib\\ext directory of the JRE.
Then System-Classpath classloader
loads all classes and jars specified by the CLASSPATH environment variable (Does this loading takes into account the Order and Export
order of libraries?)
Please correct me if I'm wrongly interpreting things here as I'm just newbie trying to understand the ClassLoading maze.
You often mention the "order and export". I assume you mean the same named tab in the project classpath dialog. As far as I know this concerns only the visibility of the projects library for other projects which depend on this project. It has nothing to do how eclipse itself is bootstrapped.
