I'm running wro4j-maven-plugin 1.7.3 against the latest bootstrap less sources (3.1.0) and get the following exception:
Failed to execute goal ro.isdc.wro4j:wro4j-maven-plugin:1.7.3:run (default) on project dezolve-web: Exception occured while processing: ro.isdc.wro.WroRuntimeException: Could not execute the script because:

I get the same problem in m2e - it this relating to Bootstrap needing a newer version of LESS?
As per @alexo's comment above, changing using the less4j processor over the lessCss processor has resolved this issue.
So my wro.properties now looks like:
preProcessors=cssImport,semicolonAppender
postProcessors=less4j,cssMinJawr
