Create your own .jar file

I have been playing with the ScriptMaster plug-in for the last few days and was stumbling through creating a .jar file with my own code, which could be accessed from any function. Since I did not find any information on how to do this in this forum, I thought I would add my findings here...

I used the 'CreateFolder' function included with ScriptMaster as an example.

1. Write Class Code

class MyFunctions{

    def CreateFolder(path){

        File dir = new File(path);

        if( dir.exists() ) return false;

        if( dir.mkdirs() ) { //Success!

            return true;

        } else { //Figure out why it failed

            File realParent = dir;

            while( realParent != null && ! realParent.exists() ) {

                realParent = realParent.getParentFile();

            }

            if( realParent != null && !realParent.canWrite() ) {

                throw new FileNotFoundException("Directory " + dir.getAbsolutePath()

                    + " could not be created because the parent directory "

                    + realParent.getAbsolutePath() + " is not writeable" );

            } else {

                throw new FileNotFoundException("Directory + " + dir.getAbsolutePath()

                    + " could not be created because of an unknown error." );

            }

        }

    }

}

Save File As: MyClasses.java

the class name should begin with an uppercase letter (or so I read somewhere)





2. Compile

• Download Java JDK
• Download Groovy *
• To Compile: run from the command line:

groovyc MyClasses.java

• (this will create a MyClasses.class file)

3. Create .jar file run from the command line:

jar cf MyJar.jar MyFunctions.class

• (this will create a MyJar.jar file)

4. Add .jar to ScriptMaster.fp7, test

• go to 'Jar Libraries'
• create new record, insert the MyJar.jar file
• go to 'ScriptMaster Modules'
• create a New Record, give your test function a name
• select the MyJar.jar file on the 'Jars' tab
• create a parameter named: pathToCreate
• enter this code for the function

  
  

example = new MyFunctions()

example.CreateFolder(pathToCreate)

cross your fingers **, hoping it will work, then run the script

* Groovy is optional, you could write your class entirely in Java, then use 'javac' to compile rather than 'groovyc'

** finger crossing is also optional
