sourcemap is likely to be incorrect

[goumang2010]

In babel plugin options, I ignore some files, then rollup tell me:

Sourcemap is likely to be incorrect: a plugin ('babel') was used to transform files, but didn't generate a sourcemap for the transformation.

And the generated sourcemap is wrong indeed(not contain the ignore files)
How can I get the full sourcemap that includes the ignored files of babel plugin?

The following is my babel plugin option:

{
    babelrc: false,
    "presets": [
        ["latest", {
            "es2015": {
                "modules": false
            }
        }]
    ],
    "ignore": [
        "dist/*.js",
        "vendor.js"
    ],
    "plugins": [
        "external-helpers"
    ],
    externalHelpers: true
}

Closing this as outdated, I hope you have resolved your issue by now. If not - feel free to open new issue.

@goumang2010 Did you fix this then. I am getting the exact same problem on new version of this plugin (4.0.0-beta.4). Exactly the same thing:

Sourcemap is likely to be incorrect: a plugin ('babel') was used to transform files, but didn't generate a sourcemap for the transformation.

After added an ignore.

@ssimpo could u create a simple repro?

@Andarist I in the middle of a project right now but will try to in the next few weeks. So, sorry for commenting then offering no further help! Since, there are only two people commenting here I figure it can't be super urgent (probably something obscure we are both doing that triggers it).

I'll also, have a dig around to see if I can see where it is coming from. The project I am getting these errors on is quite large and would have to extract some sort of test repo. I can probably reproduce some of the work flow that is generating this in a test repo to see if the error is reproduced.

I created an example repo, I am hero :P and opened a new issue
