How to redirect output from Groovy script?

groovy, java

Solution

Try this using Binding

public void exec(File file, OutputStream output) throws Exception {
    Binding binding = new Binding()
    binding.setProperty("out", output) 
    GroovyShell shell = new GroovyShell(binding);
    shell.evaluate(file);
}

After comments

public void exec(File file, OutputStream output) throws Exception {
    Binding binding = new Binding()
    binding.setProperty("out", new PrintStream(output)) 
    GroovyShell shell = new GroovyShell(binding);
    shell.evaluate(file);
}

Groovy Script

def name='World'
out << "Hello $name!"

Problem

I wonder if there is any way I could change the default output (System.out) for the groovy script that I'm executing from my Java code. Here is the Java code: ``` public void exec(File file, OutputStream output) throws Exception { GroovyShell shell = new GroovyShell(); shell.evaluate(file); } ``` And the sample groovy script: ``` def name='World' println "Hello $name!" ``` Currently the execution of the method, evaluates scripts that writes "Hello World!" to the console (System.out). How can I redirect output to the OutputStream passed as a parameter?
