I'm trying to use groovyc, but something is not right:
>echo println("Hello world") > test.groovy
>groovy test.groovy
Hello world
>groovyc test.groovy
>java -cp C:\utils\groovy-1.8.1\embeddable\groovy-all-1.8.1.jar test
Error: Could not find or load main class test
>dir test.class
...

What am I missing?

Groovy scripts can use any Java classes. They can be compiled to Java bytecode (in . class files) that can be invoked from normal Java classes. The Groovy compiler, groovyc, compiles both Groovy scripts and Java source files, however some Java syntax (such as nested classes) is not supported yet.
When you specify the classpath with -cp switch, its default value (current directory) is overwritten and so JVM can't find your class.
Add current directory to classpath, and everything works:
>java -cp C:\utils\groovy-1.8.1\embeddable\groovy-all-1.8.1.jar;. test
Hello, world
Make sure that if you are using a unix based system (Linux or Mac), then you need colon instead of semicolon for classpath entry separator:
>java -cp /path/to/groovy/embeddable/groovy-all-1.8.1.jar:. test
Hello, world
