TestNG plugin 7.8.0 requires that I add slf4j to classpath about testng-eclipse HOT 9 CLOSED

@JFK-DXML , thanks for reporting the issue, i can reproduce it on eclipse 2023-09 as well, let me see how to fix it

from testng-eclipse.

oh, wait, i got a different error not relate to this.

from testng-eclipse.

@JFK-DXML , the slf4j jar is in the testng-p2 update site https://github.com/testng-team/testng-p2-update-site/tree/main/updatesites/7.8.0.r202306071539/plugins

pls double check if it's on your installed plugin list

from testng-eclipse.

@JFK-DXML do you see any error on the "Error Log" view

from testng-eclipse.

I have the same, I had initially reported it at #533 (post) and I was rightfully pointed here so I'm reporting it here.

I am using the plugin v. 7.8.0 but I'm getting the same error:

Since I don't need this logger, I used the workaround of adding (as external jar) to the build path of the project that contains these tests the slf4j-api jar (https://www.slf4j.org/download.html), so now I just get a warning that it's using a no-op logger implementation (see https://www.slf4j.org/codes.html#noProviders for actual logging).

Eclipse 2023-09 (4.29.0, Build id: 20230907-1323), Windows 10 Pro.

java.specification.version=17
java.vm.vendor=Eclipse Adoptium
sun.arch.data.model=64
java.vm.specification.version=17
java.runtime.version=17.0.7+7

I get no errors in the Error Log after I run the problematic test:

However I do get a TestNG-related error there when I do "Check for updates":

Re the plugin list mentioned above by @missedone, I do have that plugin. This is the list filtered by typing "slf":

This is what I have under "Available Software Sites" (list filtered by typing "testng"):

I did not try to manually add the update site mentioned above by @missedone because I don't want a workaround of adding an update site address specific to a given version (I prefer to keep my workaround of manually adding the slf4j-api jar (https://www.slf4j.org/download.html) to the build path as it's more likely that I will remember to remove it when this error is fixed), but if that helps I can do that and report the outcome.

Could you share the detail of the message field in the screenshot, most important is the classpath list in the message

from testng-eclipse.

closing this as 7.9.0 should have solved this issue.

see #561 (comment)
