Referring to things like unusual command line options as "incantations" has been reasonably common across the history of computer usage at least from the 1970s or so, if not earlier.

I was going to say: "first things first: learning your tools is the 1st step" but I see it's been told already.

This is just a rant and personally I can't sympathize with. How that is a newsworthy is another issue, though.

you're kidding me, right? rhodey@rhodey$ mvn package rhodey@rhodey$ java -jar .jar

I don't think you read the article. You don't address his certificate issues. Your solution also requires writing a pom.xml which is non-trivial.

Maven can generate one for you:

  mvn archetype:generate -DgroupId=com.mycompany.app -DartifactId=my-app -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false
Which is not trivial I suppose, but it is pretty easy to do.

"Dear Java: I can run Ru­by and Python and Go and JavaScript and C code from the com­mand line on my Mac." - to be fair most of those languages are scripting languages.

In my opinion, the difference between "scripting" languages and other languages hasn't been relevant for about a decade.

Scripting languages are those that the code gets thrown away when the application gets rewritten in C, C++, Java, C#, ... in order to perform properly.

Yup, he's right. Most of these problems have been solved with tools, not by the JDK. If I have arbitrary Java that I want to execute quickly I write a unit test, not a test program for precisely this reason.

I guess it doesn't slow me down, because I know the unit test 'trick', in the same way as I know how to get Light Table to execute arbitrary s-expressions to get around Clojures load times has meant that I'm far less obsessed with Clojures slow startup.

Its a problem, sure, but I don't think Java is broken, its just never had the CLI in mind.

In java to be able to crawl a https url you have to do the following - http://www.coderanch.com/t/134619/Security/JDK-trust-Certifi... Its easier in other languages but its not that hard in java. Just export certificate via IE and save to disk and from the jre/lib/security folder and issue one command keytool -import -alias mycert -keystore cacerts -file d:\mycert.cer. (default password is changeit) Done.
