Could you please include an example (attachments) of the original code + what was the result ? Also please include your settings (indentation + formatting) for Java -- introduce method seems to work acceptably in my environment, so I need to check your specific setup. Thanks.

Ok. Here goes code sample: Select code from the line starting with XmlElement to the line starts 'plugin', right click refactor/Introduce method

 
public class JavaApplication37 {

 
    public static void main(String[] args) { 
    }

     
    public void someMethod() {
        System.out.println("testSqlMapUpdateByPrimaryKeySelectiveElementGenerated");
        XmlElement element = new XmlElement("update");
        element.addAttribute(new Attribute("id", "actualizarCliente"));
        element.addAttribute(new Attribute("parameterType", CLASE_CLIENTE));
        element.addElement(new TextElement("update cliente "));

        XmlElement setElem = new XmlElement("set");
        element.addElement(setElem);

        XmlElement elemIsNotNull = new XmlElement("if");
        elemIsNotNull.addAttribute(new Attribute("test", "cliNombre != null"));
        elemIsNotNull.addElement(new TextElement("cli_nombre = #{cliNombre,jdbcType=VARCHAR},"));
        setElem.addElement(elemIsNotNull);

        elemIsNotNull = new XmlElement("if");
        elemIsNotNull.addAttribute(new Attribute("test", "cliActivo != null"));
        elemIsNotNull.addElement(new TextElement("cli_activo = #{cliActivo,jdbcType=BIT},"));
        setElem.addElement(elemIsNotNull);

        elemIsNotNull = new XmlElement("if");
        elemIsNotNull.addAttribute(new Attribute("test", "fechaCrea != null"));
        elemIsNotNull.addElement(new TextElement("fecha_crea = #{fechaCrea,jdbcType=TIMESTAMP},"));
        setElem.addElement(elemIsNotNull);

        elemIsNotNull = new XmlElement("if");
        elemIsNotNull.addAttribute(new Attribute("test", "fechaModif != null"));
        elemIsNotNull.addElement(new TextElement("fecha_modif = #{fechaModif,jdbcType=TIMESTAMP},"));
        setElem.addElement(elemIsNotNull);

        elemIsNotNull = new XmlElement("if");
        elemIsNotNull.addAttribute(new Attribute("test", "usuarioCrea != null"));
        elemIsNotNull.addElement(new TextElement("usuario_crea = #{usuarioCrea,jdbcType=VARCHAR},"));
        setElem.addElement(elemIsNotNull);

        elemIsNotNull = new XmlElement("if");
        elemIsNotNull.addAttribute(new Attribute("test", "usuarioModif != null"));
        elemIsNotNull.addElement(new TextElement("usuario_modif = #{usuarioModif,jdbcType=VARCHAR},"));
        setElem.addElement(elemIsNotNull);

        element.addElement(new TextElement(
                "where cli_id = #{cliId,jdbcType=INTEGER} "
                + "and emp_id = #{empId,jdbcType=INTEGER}"));

        plugin.sqlMapUpdateByPrimaryKeyWithoutBLOBsElementGenerated(element, tabla);

        String attrParamType = obtenerValorAtributo("parameterType", element);

        assertEquals(attrParamType, "map");

        String sqlActual = obtenerSql(element);

        String sqlEsperado = "update cliente "
                + "set cli_nombre = #{bean.cliNombre},"
                + "cli_activo = #{bean.cliActivo},"
                + "fecha_modif = now(),"
                + "usuario_modif = #{usuNombre},"
                + "estado = 1 "
                + "where cli_id = #{bean.cliId} "
                + "and emp_id = #{bean.empId}";

        System.out.println("Sql actual = " + sqlActual);
        System.out.println("Sql esperado = " + sqlEsperado);
        assertEquals(sqlEsperado, sqlActual);
    }

}

The refactored method doesn't respect new lines:

 private XmlElement newMethod() {
        XmlElement element = new XmlElement("update");
        element.addAttribute(new Attribute("id", "actualizarCliente"));
        element.addAttribute(new Attribute("parameterType", CLASE_CLIENTE));
        element.addElement(new TextElement("update cliente "));
        XmlElement setElem = new XmlElement("set");
        element.addElement(setElem);
        XmlElement elemIsNotNull = new XmlElement("if");
        elemIsNotNull.addAttribute(new Attribute("test", "cliNombre != null"));
        elemIsNotNull.addElement(new TextElement("cli_nombre = #{cliNombre,jdbcType=VARCHAR},"));
        setElem.addElement(elemIsNotNull);
        elemIsNotNull = new XmlElement("if");
        elemIsNotNull.addAttribute(new Attribute("test", "cliActivo != null"));
        elemIsNotNull.addElement(new TextElement("cli_activo = #{cliActivo,jdbcType=BIT},"));
        setElem.addElement(elemIsNotNull);
        elemIsNotNull = new XmlElement("if");
        elemIsNotNull.addAttribute(new Attribute("test", "fechaCrea != null"));
        elemIsNotNull.addElement(new TextElement("fecha_crea = #{fechaCrea,jdbcType=TIMESTAMP},"));
        setElem.addElement(elemIsNotNull);
        elemIsNotNull = new XmlElement("if");
        elemIsNotNull.addAttribute(new Attribute("test", "fechaModif != null"));
        elemIsNotNull.addElement(new TextElement("fecha_modif = #{fechaModif,jdbcType=TIMESTAMP},"));
        setElem.addElement(elemIsNotNull);
        elemIsNotNull = new XmlElement("if");
        elemIsNotNull.addAttribute(new Attribute("test", "usuarioCrea != null"));
        elemIsNotNull.addElement(new TextElement("usuario_crea = #{usuarioCrea,jdbcType=VARCHAR},"));
        setElem.addElement(elemIsNotNull);
        elemIsNotNull = new XmlElement("if");
        elemIsNotNull.addAttribute(new Attribute("test", "usuarioModif != null"));
        elemIsNotNull.addElement(new TextElement("usuario_modif = #{usuarioModif,jdbcType=VARCHAR},"));
        setElem.addElement(elemIsNotNull);
        element.addElement(new TextElement(
                "where cli_id = #{cliId,jdbcType=INTEGER} "
                        + "and emp_id = #{empId,jdbcType=INTEGER}"));
        return element;
    }
