To acquire such a wonderful skill, please see this one: How to include jar files with java file and compile in command promptĪmongst those three ways, the recommended one is to get to know with build tools such as Apache Maven or Gradle. class files including the downloaded jar. The next thing you need to do is to learn how to compile your Java code to. You will want to search the maven central repository (see: ) and from there download your. What you need to do is to find the required dependency jar package. There are plenty of tutorials on SO that tell you how to do this, so I'll simply summarize and indicate the resources. I also encourage you to get your hands on Apache Maven docs, as it is quite readable and transparent.Īnd the last way I can think of is to manually compile your application and include the required dependency during the compilation process. Of course Apache Maven is not a lightweight tool so you would have to take some time to learn how to build code with it. Your pom would look something like this: In your project you would then have a pom.xml file and you would simply look-up the needed dependency in Maven Central repository, add it to your dependencies section in pom.xml file and build the application. You should definitely check those guys out, as they are insanely useful when it comes to building Java code and, sooner or later, you will probably start using them anyway. jgraspportable.bat only applies if you are running jGRASP in portable mode (usually installed on a USB stick). The second way you could do this is to build your program with build automation tool, such as Apache Maven or Gradle. For jGRASP itself, use 'Settings' -> 'jGRASP Startup Settings' on Windows or Mac. And that would be the first and most beginner-friendly way, unfortunately I haven't a faintest idea about JGrasp so I'm going to focus on other solutions. Introduction to jGRASP - opening files, compiling and running programs, adding line numbers, generating the control structure diagram (CSD), and running programs in the debugger. Then, your IDE would compile the code with given dependency on a class path and problem would be solved. In the majority of IDEs (in your case we are talking about JGrasp) there is a way to add a dependency to the project directly. In order to overcome error mentioned in a question, you need to have javax.activation module dependency on your class path. You can find more about class paths here. Graphical User Interface (GUI): An effective GUI enables an intuitive programming interface.Broadly speaking, a dependency is code (often written by someone else) which your application needs to compile.Ī dependency in your case, is a java library which has classes that need to be on your class path.
