Bad output on widgetset compilation failures.

[Peppe]

When you compile widgetset, and it fails, the output is very hard to understand. You get "Failed to execute command [[
a-a4-size-command-to-gwt-compiler-with-all-parameters
]]"

For example in eclipse -> maven -> update project, the error message will be only maven issue -> "Failed to execute command [[" because it only takes the first row and cuts away everything after newline.

You have absolutely no clue here what have gone wrong or that it is even related to widget set. The error message should be a lot clearer to point you in the correct direction. Printing the whole command out in any case in unneccesary because you get it anyhow visible by running maven with the -X parameter.

In my case it was a missing pro tool license. In some other case it is a malformed parameter. Third it is a missing gwt.xml.

Changing the output to "Widgetset compilation failed" would already be an upgrade on an MVP level.
