Jenkins pipeline: No such DSL method

Question

With this code i got an error in Jenkins pipeline. I don`t get it why? Am I missing something?

node {
   stage 'test'
   def whatThe = someFunc('textToFunc')
   {def whatThe2 = someFunc2('textToFunc2')}
}


def someFunc(String text){
    echo text
    text
}
def someFunc2(String text2){
    echo text2
    text2
}

Error:

java.lang.NoSuchMethodError: **No such DSL method 'someFunc'** found among [archive, bat, build, catchError, checkout, deleteDir, dir, echo, emailext, emailextrecipients, error, fileExists, git, input, isUnix, load, mail, node, parallel, properties, pwd, readFile, readTrusted, retry, sh, sleep, stage, stash, step, svn, timeout, timestamps, tool, unarchive, unstash, waitUntil, withCredentials, withEnv, wrap, writeFile, ws]

Answer 1

remove the extra brackets from around the sumfunc2 invocation:

node {
   stage 'test'
   def whatThe = someFunc('textToFunc')
   def whatThe2 = someFunc2('textToFunc2')
}

def someFunc(String text){
    echo text
    text
}
def someFunc2(String text2){
    echo text2
    text2
}

Update:

In Groovy if a method's last argument is of type Closure, then when calling the method the closure can be outside of the brackets like:

def foo(whatever, Closure c) {}

// Can be invoked as
foo(whatever, {
    // This is the second argument of foo of type Closure
})

// It is also the same as writing
foo(whatever) {
    // This is the second argument of foo of type Closure
}

The reason that the original throws is because the following code

def whatThe = someFunc('textToFunc')
{def whatThe2 = someFunc2('textToFunc2')}

is the same code as

def whatThe = someFunc('textToFunc') {
    def whatThe2 = someFunc2('textToFunc2')
}

This means that what the interpreter will be looking for is

someFunc(String text, Closure c)

and there is no such method
