Seems that lombok does not support Java 8 compiler. I have this simple source code:

package java8test;

import lombok.Getter;

public class GetterTest {

@ Getter
private int i;

}

I am trying Lombok 0.11.6 from https://projectlombok.org/ and javac:
$ javac -fullversion
javac full version "1.8.0-ea-b76"

Trying to compile the source code leads to an exception/warning:
$ javac -classpath lombok.jar GetterTest.java
GetterTest.java:5: warning: Can't initialize javac processor due to (most likely) a class loader problem: java.lang.NoClassDefFoundError: com/sun/tools/javac/code/TypeTags

Note that daily/trunk builds of NetBeans are currently using javac from JDK8, and so lombok does not work on them:
http://netbeans.org/bugzilla/show_bug.cgi?id=226165

Note this does not apply to NetBeans 7.3, which is using JDK7 javac.

As a user of netbeans dev builds and a user of lombok also, i would be very glad to see support for jdk8 in lombok anytime soon!

Any news on this fix yet? :)

[lombokissues]

👤 grootjans   🕗 Apr 22, 2013 at 21:44 UTC

working hard on this, though limited by the free time we invest.

Though JDK8 support is simple enough if we would completely fork lombok for jdk8, or drop support for all previous JDKs, this is just not how we would want this to work. This would also imply using a different lombok jar in netbeans runtime and in the build.

Why is building it in one jar hard? We rely/need the internal AST of javac. In JDK8 they made some changes that are great for the AST, among others introducing actual enums for their constants, but less great for us. We have to make sure that we support, on runtime, both compiler versions.

We're halfway there at this moment, with a few pesky problems to go, and then the challenge to adapt our build to test against JDK8. Untill now we used openJDK builds to test against, but there isn't a build of that yet for us to readily use.

so, stay tuned. This definitely has our attention.

👤 grootjans   🕗 Apr 27, 2013 at 07:49 UTC

there is a branch on github, where lombok is developed, but no snapshot channel with our maven repo provider.

At this point in time, though, this branch is in the wonderful state that it supports neither Java 7 or Java 8.

There is any chance to you make available a SNAPSHOT version which works for JDK 8? IMHO you can make available a version which works only at JDK 8 for now, at least for us which wants to make some tests. Thanks in advance.

We're working on it. We will expect to have something testable within a few weeks. That might sound like a lot of time, but there is a lot to be fixed and we only have so much time :-(

[lombokissues]

👤 reinierz   🕗 Sep 09, 2013 at 22:13 UTC

For the fans: We've got an initial release that retains its compatibility (including the new 'copy javadoc from field to generated getters/setters' stuff we've had some issues with) for JDK6/JDK7, and which also works on JDK8, though there are a select few corner cases that don't work yet, including some val corner cases, and the aforementioned javadoc copying thing which simply won't happen when delomboking with a JDK8's javac in your tools.jar of the VM you're running delombok on.

Edge release is available here: https://projectlombok.org/download-edge.html

Please let us know if this works for you, or if it doesn't!

NB: It's time to go to bed; no time yet to test if this actually works on netbeans. Many kudos for the first one to chime in if this'll do it for recent netbeans releases, though!

Hi folks,
I have tested with a newly built NetBeans without success. Maybe I am doing something wrong with lombok, but maybe not :)

First of all, I created a project with NetBeans 7.3.1 using lombok-edge with success and just tried to open it at NetBeans trunk build, but with the following error in the IDE log file:

Okay, we found it. Turns out calling JavaCompiler.version() doesn't return "1.8" as you might expect, but "(version info not available)". Dunce hat to team netbeans for that marvellous implementation of the 'version()' method. We found an alternate slightly hacky way (inspect the valid options for the -source parameter and parse the last one in the enum), which seems to be holding up. We only use it if the JavaCompiler.version() call produced a silly result.

We'll try and push an updated edge release out the door later today, we have some debug work to undo :)

Yes, I know. I have been working with NetBeans team for more than a decade with huge success. I already have all the papers signed for OCA and so on, so if it really is a NetBeans issue, I am pretty sure we can handle it in NetBeans side too. I will take a look at this one today yet and maybe submit something asap. If you give me some coordinates at you code base, it gonna be easier to me. I hope I can handle NetBeans easier since I am already used to.

@ michel.graciano: Yup, the resource file that contains the version stuff just isn't there, for some reason. The relevant code line is JavaCompiler's private static String version(String key) method. It loads resource "com.sun.tools.javac.resources.version", and it isn't there in netbeans's internal javac.

Hey guys, tested with success in NetBeans 7.4 daily build. Tomorrow I will test it more at work, with a bigger project (here I have just some test and simple projects), but so far so good. If some face some issus, you need just to remove your index cache (http://wiki.netbeans.org/FaqWhatIsUserdir). Thanks again guys.

Lombok has released a stable version with this fix, but looks like we have a regression here. I am not sure if it is a regression from NetBeans or Lombok side, so I have filed in both projects. The Lombok issue is issue #626.

@rasenderhase not related; you're merely getting the same error because lombok identifies java version 10-EA as unknown, falling back to thinking it must be a JDK6, which it isn't. Roel already fixed this part.
