How to load the file from the inputstream?

Question

I have the following code:

InputStream in = this.getClass().getClassLoader().getResourceAsStream("test.groovy");

I need to pass this resource to the method called parse which takes File as param, so doing so fails:

new GroovyShell().parse(new FileInputStream(in));

How I can convert FileInputStream to File in java?

Answer 1

您实际上可以使用： GroovyShell #parse（Reader）方法：

Script result = new GroovyShell().parse(new InputStreamReader(in));

Answer 2

use this :

try {
    URL url = this.getClass().getClassLoader().getResource("test.groovy");
    File file = new File(url.toURI());
    new Shell().parse(file);
} catch(...){...}

if you know exact path to "test.groovy", do this:

new Shell().parse(new File("path/to/test.groovy"));
