Hello all, I'm really brand new to Groovy and I'm trying to get something done. I've written some Groovy code (which works just fine) which receives some text. This text should be an integer (between 0 and 10). It may just happen a user enters something different. In that case I want to do some specific error handling. Now I'm wonderin...
I'm implementing in Groovy a DSL for some existing file format. In this format we have a construct like group basic_test { test vplan_testing { dir: global_storage; }; }; And here I have problem with this dir: global_storage - groovy considers "dir:" as a label, so I can't handle it. Do you have an idea how I can rec...

This is weird: using groovy strings to hold some command lines for execution, I find that sometimes if there are quote characters inside the string, the execution simply silently fails. WTF? (Updated, see below.) Here's my test program: print " 1: " ; "grep nameserver /etc/resolv.conf".execute().text.eachLine {println it } ...
