JS Folder is empty

[Memz-idk]

So, I followed the http://www.jsweet.org/eclipse-plugin/ tutorial but the js folder is empty, the .jsweet folder was created but I checked the .jsweet/candies/src and it was empty(Idk if it's supposed to be empty but probably not), I tested it on a dynamic web project but even on a normal project project it doesn't work, everything else seems to be working

Hello @Memz-idk
Thanks for reporting. Which version of Eclipse, Java are you using?

Hello @Memz-idk

I'm using 2020-03 (4.15.0)

[lgrignon]

Java version please :)

[Memz-idk]

Java version please :)

As far as I tested it doesn't matter that much but i'm using 1.8.0_231

[lgrignon]

It's kind of important because Eclipse plugin is not compatible with Java 9+ :)

Do you launch Eclipse with JDK or JRE. Please try JDK if you launch it with JRE.

Do you have any error in Eclipse error log?

Thanks

Ok I tested again and I found this error in the logs

It is not compatible with java over 8, please try with jdk 8 and post here your error if any

Same error :/

[lgrignon]

I strongly recommend you to use https://github.com/lgrignon/jsweet-maven-plugin which is up to date with latest 3.0.0-RC8
(but also 2.3.10 if you want to stick with Java 8).
Maven plugin can be integrated in Eclipse, and there is a watch mojo which is pretty handful.

Anyway, it would be great to refresh Eclipse JSweet plugin, even if it's not a priority. For instance, it could use the latest JSweet version and ensure it supports recent Eclipse versions.

Another important point for you if you want to try again with current plugin:

• did you use openjdk? JSweet 2 requires Oracle JDK if my memory is correct
• candies directory can be empty if you do not reference any candy in your project's dependencies (candies are JSweet jars)

I also followed the plugin tutorial as mentioned in the initial comment and same error here:

Digging into the https://github.com/cincheo/jsweet-eclipse-plugin repository I realized that the plugin installed from the update site is pretty old (2019-04-22), since http://eclipse-update-site.jsweet.org/site.xml points to version 0.9.6.20190422, although there is a more recent commit 5aac78d which includes an almost up-to-date transpiler.

Thus I built the plugin myself from the above mentioned commit and lo and behold it works.

I'm running the eclipse-java-2021-03-R-linux-gtk-x86_64.tar.gz with the prepackaged jre (plugins/org.eclipse.justj.openjdk.hotspot.jre.full.linux.x86_64_15.0.2.v20210201-0955/jre/bin/java) on Debian Buster.

My sample jsweet project itself uses the default jre from Debian:

openjdk 11.0.11 2021-04-20
OpenJDK Runtime Environment (build 11.0.11+9-post-Debian-1deb10u1)
OpenJDK 64-Bit Server VM (build 11.0.11+9-post-Debian-1deb10u1, mixed mode, sharing)

Long story short: It's probably enough to build a plugin release with the new transpiler and publish it to the update site.

I tried to install JSweet plugin for eclipse, Luna Service Release 2 (4.4.2), got following error:
HTTP Server 'Internal Error': http://eclipse-update-site.jsweet.org/content.xml
HTTP Server 'Internal Error': http://eclipse-update-site.jsweet.org/content.xml
HttpComponents connection error response code 500.
Please help!

[renaudpawlak]

Service is temporary down for SSL migration. Sorry for the inconvenience but unfortunately it is complicated to migrate apparently.

Hello @minchu125
Is it better for you now? You can also try to clear DNS cache. It should be fixed right now.

Please close if it's ok
