Hi there,

First, thank for this plugin, really helpful.

I would like to report an issue: XmlPullParserException: only whitespace content allowed before start tag and not O ...

At first, I thought maybe my yaml file was invalid, but checked it with YAMLLint and it said it's valid.

Versions & OS

Sass-lint-plugin: 1.10.2
IntelliJ IDEA 2017.1 Build #IU-171.3780.107, built on March 22, 2017
JRE: 1.8.0_112-release-736-b13 amd64
JVM: OpenJDK 64-Bit Server VM by JetBrains s.r.o
Linux 4.8.0-46-generic

Context

sass-lint config:

  • Checked the Use specific config file , and verified the sass-lint.yml with YAMLLint, it's valid.
  • Filled the Path to sass-lint bin & Node interpreter

I just open any scss file, and when it starts analyzing the file, Intellij pops a notification saying an error occured with sass-lint-plugin.

Stacktrace

Here is the complete stacktrace if it can help =)

Sample SCSS file & YAML config

SCSS file throwing the error (but it occurs on every filed I opened)


@import 'mixins/label';

.label {
    display: inline-block;
	font-size: $font-size-base;
	padding: $padding-base-vertical/2 $padding-base-horizontal;

	+ .label {
		margin-left: $padding-base-vertical/2;
	}
}

.label-default {
  @include label-variant($label-default-bg);
}

.label-primary {
  @include label-variant($label-primary-bg);
}

.label-success {
  @include label-variant($label-success-bg);
}

.label-info {
  @include label-variant($label-info-bg);
}

.label-warning {
  @include label-variant($label-warning-bg);
}

.label-danger {
  @include label-variant($label-danger-bg);
}

.mui-label-remove {
	padding-left: $padding-base-horizontal;

	cursor: pointer;
}

Yaml config I pointed to in sass-lint-plugin config in Intellij:

Any clue ? =)

Thanks in advance, and again, great work !

Seeing this on Windows and macOS in PyCharm. Node 8.1.3 and sass-lint 1.11.1.

Update: I was able to resolve the problem by using a different .sass-lint.yml. The following .yml file worked:

This appears to be a bug surrounding the option formatter when set to html. Removing output-file and setting formatter to stylish seem to make WebStorm lint styles properly.

I had the same problem in AndroidStudio when I delibrately downgraded "compileSdkVersion" and "targetSdkVersion" in file build.gradle.
It cannot be fixed with "Clean Project". To fix I removed all, took an initial version of the project, applied my few desired changes, and now it works again.
