Kettle编译具有依赖项的Jar

Question

Pentaho/Kettle: Instead of running code from the code box in the "User defined Java Class", I am trying to compile it into a Jar, and run the jar file from the "User defined Java Class". I do this because my Java projects are too big, and in order to increase modularity. However, there are some problems with dependencies. Some methods are not available in the libraries, whereas there are some which are available in multiple libraries.

Zip file of the project I am trying to compile: https://drive.google.com/file/d/1H-RGGvH-h3zvLnF3qIVVIHnnB4vtwKvN/view?usp=sharing .

Code of the Gradle dependencies I am using:

dependencies {
compile group: 'com.datastax.cassandra', name: 'cassandra-driver-core', 
version: '3.1.2'

compile group: 'pentaho-kettle', name: 'kettle-core', version: '7.0.0.3-62'
compile group: 'pentaho-kettle', name: 'kettle-sdk-database-plugin', version: '7.0.0.0-25'
compile group: 'pentaho-kettle', name: 'kettle-sdk-step-plugin', version: '7.0.0.0-25'
compile group: 'pentaho-kettle', name: 'kettle-ui-swt', version: '7.0.0.3-62'

compile group: 'org.projectlombok', name: 'lombok', version: '1.16.16'

testCompile group: 'junit', name: 'junit', version: '4.11'
}

private Pattern p = null;
private FieldHelper fieldToTest = null;
private FieldHelper outputField = null;

public boolean processRow(StepMetaInterface smi, StepDataInterface sdi) 
throws KettleException
{
    Object[] r = getRow();

    if (r == null) {
        setOutputDone();
        return false;
    }

    // prepare regex and field helpers
    if (first){
        first = false;

        String regexString = getParameter("regex");
        p = Pattern.compile(regexString);

        fieldToTest = get(Fields.In, getParameter("test_field"));
        outputField = get(Fields.Out, "result");
    }

    r = createOutputRow(r, data.outputRowMeta.size());

    // Get the value from an input field
    String test_value = fieldToTest.getString(r);

    // test for match and write result
    if (p.matcher(test_value).matches()){
        outputField.setValue(r, Long.valueOf(1));
    }
    else{
        outputField.setValue(r, Long.valueOf(0));
    }

    // Send the row on to the next step.
    putRow(data.outputRowMeta, r);

    return true;
    }

}

Screenshot of some methods that are available in multiple libraries:

EDIT: Manually adding ALL of the Jars from \\data-integration\\lib\\ does not work either.

Answer 1

Did you import the methods in red ?

It is not because the file is on the classpath that the class knows it needs to import them.

That would also fix your multiple library issue, because the import specify the full path name.
