Pattern: Code block starts with empty line

Issue: -

Description

Checks that code blocks such as method bodies, closures and control structure bodies do not start with an empty line.

Example of violations:

boolean not(boolean value) {
                            // violation
    !value
}

3.times {
                            // violation
    println 'hello!'
}

for (value in []) {
                            // violation
    println value
}

for (i = 0; i < 3; i++) {
                            // violation
    println i
}

int j = 0
while (j < 3) {
                            // violation
  println j++
}

if (ready) {
                            // violation
    println 'ready'
} else {
                            // violation
    println 'not ready'
}

try {
                            // violation
    throw new Exception()
} catch (Exception e) {
                            // violation
    println 'exception'
} finally {
                            // violation
    println 'finally'
}

switch (true) {
                            // violation
    default:
        println 'switch'
}
