I was testing an ant based build script change today. And I thought ant was already retired. Running the script led to a lot of warnings about a missing library. I asked the person, if there are any dependencies for ant-contrib. His response was “yes, you need to install ant-contrib”. First of all, I didn’t have ant installed. But that was easy with irichter@irichter-MacBookPro:~ brew install ant Unfortunately, ant-contrib wasn’t available via homebrew, so I had to download it and place it… where?
