No JavaScript generated

I followed your instructions (http://www.jsweet.org/eclipse-plugin/) and successfully cloned jsweet-quickstart and made it work with maven on command line smoothly. That is already impressive. Also I could install your Eclipse Plugin and SDGB into my Eclipse Neon.1. I could add the JSweet builder and target/js, etc. was already configured properly from the start. I double checked the setting, the builders, etc. and cleaned the project many times, changed the Java source file slightly but in any time I only get output in target/ts and target/js remains empty. I am developing Java for almost 18 years now and am not stupid. It would be great if you have a hint for me what could be wrong.

BTW (you do not seem to have a forum or google group for JSweet so I write this here): I am new to JSweet but have a long GWT history and experience also experimented with dragome, etc. Also I have been through the nodejs, npm, bower, yarn, gulp, grunt, jasmine, karma, phantomJS, typescript, tsd, typings, systemjs, ... hell and I am definitely annoyed by this pain. I read your FAQs, documentation and I am absolutely amazed of what you have created. It looks like exactly the GWT successor that I have been dreaming of. Also I am an enthusiastic OSS developer and provide and contribute to various projects. I would love to write a JS port of my Bean/Properpty support as JSweet Candy (but would need further hints): https://github.com/m-m-m/util/blob/master/bean/src/main/java/net/sf/mmm/util/bean/api/Bean.java https://github.com/m-m-m/util/blob/master/bean/src/test/java/net/sf/mmm/util/bean/impl/BeanFactoryImplTest.java https://github.com/m-m-m/util/blob/master/bean/src/test/java/net/sf/mmm/util/bean/impl/example/ExamplePropertyBean.java Also I wanted to create something really huge as abstraction for JavaFx and GWT that I might want to simplify and reactivate using JSweet: https://github.com/m-m-m/util/wiki/Rescue-the-java-world

In case you want to get in contact mail to hohwille at users.sourceforge.net - Thanks

Hi there! I did not have a chance to test the JSweet plugin with Neon yet (I am using Mars). So it might just be that the plugin uses an API that was broken in Neon :( I will try to investigate but I don't have much time these days. If you have a chance to try it with Mars, that would be great.

I will email for other topics.

[hohwille]

Thanks for the quick response. I tried with mars but same problem here: Version: Mars.2 Release (4.5.2) Build id: 20160218-0600

I have JSweet Project Builder active in the Builders of the project. I clean the project and refresh target folder. The ts folder got populated but js is entirely empty.

[hohwille]

Is this warning relevant?

Version mismatch warning in not a crash issue... and I don't see anything relevant in the logs :( I will try it tomorrow and see if I can reproduce the bug. Thanks for your help.

[renaudpawlak]

Ok. It looks like I have the same problem... probably a regression :( I'll tell you when it is fixed.

[krishnamoorthya]

facing the same issue here. please let me know once it is fixed

[renaudpawlak]

Ok. There were many small issues adding up together. Basically, the checkbox to disable JavaScript generation was not working properly. I have fixed this and improved logs and workspace refreshing for better use in the future.

I have redeployed a plugin feature, so just update the plugin through Eclipse and it should work much better. (make sure that the checkbox to disable JavaScript generation is unchecked in your JSweet configuration).

[krishnamoorthya]

it worked. thanks for fixing this so quickly

[renaudpawlak]

@hohwille is it working for you? (you may need to disable the JSweet plugin and to enable it again before cleaning)

[hohwille]

Perfect. :+1: I updated and now it works as expected. Thank you so much for your fast reaction and fixes! Feel free to close this issue.

[JordanLongstaff]

I'm having the same problem. I'm using Eclipse 2019-12 and the latest version of the plugin.

[lgrignon]

Hello @JordanLongstaff I think your problem may be different and would require a new ticket.

Are you using JDK 8? JSweet Eclipse plugin uses JSweet 2.x which only supports Java 8.

[JordanLongstaff]

I wasn't, but I changed my project to JDK 8u241 and it still doesn't work.

[JordanLongstaff]

OK...first of all, one of the forks of this project actually told me that I have to run Eclipse using the JDK and not the JRE or else JSweet won't work at all (because of some BS with Maven requiring that -.-). So now, finally, JSweet can successfully generate the TypeScript files, but not JS.
