Jenkins pipeline: No such DSL method - jenkins

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

Answer 2

Since this answer is the first one I found when I lookup the "No such DSL method" message, I would like to add that it might also be the interface that is not matching. In my case the first parameter was a list, but I tried to call the method with an array. So please check your interface matches what you expect, and your parameters are passed in correctly.

Answer 3

In my case what was happening is that I was referencing a variable using: ${} that was expanding to an empty string:
env.VAR1=${VAR2}
in my case, var2 didn't really exists, so what I had to do was actually:
env.VAR1=env.VAR2.
Silly mistake from my end.

Answer 4

You may have also forgotten to in include your library...
i.e.
#Library('shared-library') _
