11 years ago The wro4j-1.6.3 uses transitively an older version of less4j. In order to upgrade, just add the less4j dependency explicitly in your pom.xml with version 1.0.0.

11 years ago This doesn't seems to work. I hacked it directly in the pom-file of wro4j in my ~/.m2-rep. However I still get

11 years ago I didn't expect it to fix your problem. But, at least the reported error logs reflect the latest version of less4j. Could you try to isolate the problems and show the offending less code with associated error message?

11 years ago I tried it with both command line less4j-1.0.0 and less4j-0.0.14 and I'm getting the same errors in both cases. It starts with this:
ERROR mixins.less 251:33 mismatched input ',' expecting ')' in abstract mixin or namespace (which started at 251:1)
ERROR mixins.less 253:12 no viable alternative at character '`'
ERROR mixins.less 253:11 no viable alternative at input '~' in expression (which started at 253:11)
ERROR mixins.less 253:44 mismatched character '\' expecting '='

...It is probably the same thing as what you are getting from wro4j.

Unfortunately this is nearly impossible to analyse because I don't know where the file is which is the result of the preprocessor. If I don't use the proprocessor I get a less file as a result. So less4j seems to do nothing.
I updated to bootstrap 2.3.1 and there it works fine as long as I use import-css.
I hope you have now all information you need. It's a nice project because it's impressive fast.

11 years ago Just for other people who have trouble with the plugin an try to update the version. The dependency must be added to the plugin section
<dependencies>
<dependency>
<groupId>com.github.sommeri</groupId>
<artifactId>less4j</artifactId>
<version>1.0.0</version>
<exclusions>
<exclusion>
<groupId>com.beust</groupId>
<artifactId>jcommander</artifactId>
</exclusion>
</exclusions>

11 years ago @opensource21 Would it be possible to use Twitter Bootstrap v2.2.0 for you? It is one version up over v2.1.1 and was released two months after it. List of changes between those two versions is here: https://github.com/twitter/bootstrap/issues?milestone=5&state=closed . I do not know whether they are important or not.
Twitter Bootstrap v2.2.0 compiles with deprecated syntax warning only, but I did not tested it beyond compiling. The commit that made it work: https://github.com/twitter/bootstrap/commit/38303dd9975a8f1bca89b9f0f8ef06a26dd3f1e0
Alternative solution: the above commit removes both issues that are causing your problem. So, if you have to use v2.1.1, you can patch it with the above commit only.

11 years ago Technical details: the problem is caused by mixin declared in mixins.less file, line 251:
.box-shadow(@shadowA, @shadowB:X, ...){
// Multiple shadow solution from http://toekneestuck.com/blog/2012/05/15/less-css-arguments-variable/
@props: ~`"@{arguments}".replace(/[\[\]]|\,\sX/g, '')`;
-webkit-box-shadow: @props;
-moz-box-shadow: @props;
box-shadow: @props;
}.box-shadow(@shadowA, @shadowB:X, ...). I opened separate bug for it for easier tracking: https://github.com/SomMeri/less4j/issues/129 It should be easy to fix.Twitter bootstrap v2.1.1 uses JavaScript to render box shadow, that feature was not implemented yet: https://github.com/SomMeri/less4j/issues/22 Line with JavaScript:
~`"@{arguments}".replace(/[\[\]]|\,\sX/g, '')`Switched to 2.3.1, so it's fine to me. How ever it's good that you work on all that issues. From my point of view you can close the issue.

11 years ago Thank you for reporting the issue. Mixins arguments bug is fixed and jCommander dependency is now optional. I will try to release new fixed version 1.0.1 today.
JavaScript evaluation is still open. Less.js is trying to discourage JavaScript in .less files as much as possible, so it is not priority right now. It's priority will go up if someone votes for that issue. If you need it, let me know.
Closing the issue, since the only remaining problem is tracked elsewhere.
