You have a scope problem and need to move the logger declaration into
your A class. Also if slf4j is not available in your classpath, @Grab is
your friend.
The following works when running the script in the GroovyScriptEngine:
@Grab('org.slf4j:slf4j-simple:2.0.16')
import org.slf4j.LoggerFactory
import org.slf4j.Logger
class A {
Logger logger = LoggerFactory.getLogger("l")
public A() {
logger.info("L")
}
}
A a = new A()
Note: I don't know how OpenHAB is executing the Groovy code. If it is
using the GroovyShell then use
groovy.grape.Grape.grab('org.slf4j:slf4j-simple:2.0.16') instead.See
https://docs.groovy-lang.org/latest/html/documentation/grape.html for
details.
Hope this helps.

Hello,
OpenHAB 4.2.1 is written in Java and has a Groovy 4.0.11 plugin to programme
logic. It allows writing code outside of classes, which is executed
immediately. When I place a file openhab/jsr223/test.groovy:
import org.slf4j.LoggerFactory
logger = LoggerFactory.getLogger("l")
class A {
public A() {
logger.info("L")
}
}
A a = new A()
the system logs
2024-08-21 12:15:21.061 [ERROR] [ipt.internal.ScriptEngineManagerImpl] - Error
during evaluation of script ‘/etc/openhab/automation/jsr223/test.groovy’:
javax.script.ScriptException: groovy.lang.MissingPropertyException: No such
property: logger for class: A
How can I make logger visible within the methods of class A, without passing it
as parameter to the constructor?
