Getting xstream error 'com.sasslint.cli.SassLint' in Webstorm 2016.2.3

[bdugan14]

Whenever I start Webstorm, I'm getting an error that I'm having trouble making sense of

It appears the linter isn't working on my machine. My settings are as follows:

My sass-lint is version 1.9.1.

Have others run into this error? If this is an issue w/ my configuration of the plugin, it would be helpful to have a more descriptive error message if possible. Thanks!

Was able to solve this issue thanks to a suggestion from one of my coworkers, I'll post the solution here:

When downloading/unzipping the file from the webstorm site, we receive 2 .jar files inside the 'lib' folder: one for sass-lint-plugin, and one for the xstream dependency

I had this issue when I tried to install the plugin from WebStorm's 'Install From Disk... interface:

This only lets you select 1 .jar file... so I hoped that some wizardry would also pull the xstream dependency to the right place as well, but this doesn't appear to be the case.

To fix the error, I combined the two .jar files into a single .jar file, using this method: http://stackoverflow.com/questions/5080220/how-to-combine-two-jar-files

from the 'lib' directory of the 'sass-lint-plugin' folder: (version numbers may be different for different editions of this plugin)

$ mkdir tmp $ (cd tmp; jar -xf ../sass-lint-plugin.jar) $ (cd tmp; jar -xf ../xstream-1.4.7.jar) $ jar -cvf sass-lint-combined.jar -C tmp .

Then, uninstall any existing, broken instances of Sass Lint, and install the newly-combined sass-lint-combined.jar.

This worked for me!

If at all possible, it would be helpful if the .jar delivered from the JetBrains website automatically contained xstream and sass-lint-plugin bundled together. I'll take a look at it myself on Monday but... I don't know any Java so it's a bit of a longshot :)

bdugan14- I tried your rebundling hack, and I still get errors. My stopgap is to use the scss-lint plugin. This should help all issues 11 - 15 which seem to be related.

I am using IntelliJ Ultimate 2016-3 with sass-lint plugin v1.0.5, sass-lint v1.9.1 and get a bit different warnings (which seem the same, as before your hack):

was the stack trace you posted above the error you encountered before making any changes/trying the rebundling hack? If so, this doesn't look like the same error I encountered.

After the rebundling hack.
