Configure Javascript Errors/Warnings

[m-froehlich]

I am using the latest Eclipse 2025-06 (4.36.0), Build id: 20250605-1316
The used download is "for Java Enterprise and Web Development", though stripped some unwanted plugins.

Wild Web Developer HTML, CSS, JSON, Yaml, JavaScript, TypeScript, Node tools 1.3.10.202502071606

When I open a .js file with the following content:

let table = document.createElement( "table" ); table.cellSpacing = "0"; table.cellPadding = "0";

the tokens "cellSpacing" and "cellPadding" are marked with a warning:

'cellSpacing' ius deprecated [6385]
resp.
'cellPadding' ius deprecated [6385]

I would like to configure the errors and warnings for JavaScript files and in case of doubt disable that feature completely. I have Sonar JS validating in place and configured. I don't need redundant Eclipse validating here.

So, how can I configure that? I can't find any preferences pages for that.

For me it is not marked as a warning but as an info marker.

You can disable the markers by disabling typechecking of JS files via jsonconfig.json in the project root:

{
  "compilerOptions": {
    "checkJs": true
  }
}

You can then for example configure eslint checks instead to your likings.

If you have SonarQube / SonarLint plugin installed it will also flag this deprecation warning.
