QUESTION
I'm trying to write a library called "Visione" in Processing using the processing-library-template here.
Unfortunately Eclipse gives me the following error:
...ANSWER
Answered 2017-Apr-07 at 02:57If you're in a class other than your main sketch, you can't access Processing's functions directly.
Instead, you'd probably want to pass a PApplet
reference into your class, and use that to call Processing's functions. Something like this:

Install processing-library-template
Add Processing to the project build path.
Open your project's "Properties" window.
Under "Java Build Path", select the "Libraries" tab and then "Add External JARs...".
Locate and add Processing's core.jar to your build path. It is recommended that a copy of core.jar is located in your Eclipse workspace in a libs folder. If the libs folder does not exist yet, create it. Read the section below regarding where to find the core.jar file.
Confirm the setup with "OK".
Edit the Library properties.
Open the resources folder inside of your Java project and double-click the build.properties file. You should see its contents in the Eclipse editor.
Edit the properties file, making changes to items 1-4 so that the values and paths are properly set for your project to compile. A path can be relative or absolute.
Make changes to items under 5. These are metadata used in the automatically generated HTML, README, and properties documents.
Compile your Library using Ant.
From the menu bar, choose Window → Show View → Ant. A tab with the title "Ant" will pop up on the right side of your Eclipse editor.
Drag the resources/build.xml file in there, and a new item "ProcessingLibs" will appear.
Press the "Play" button inside the "Ant" tab.
BUILD SUCCESSFUL. The Library template will start to compile, control messages will appear in the console window, warnings can be ignored. When finished it should say BUILD SUCCESSFUL. Congratulations, you are set and you can start writing your own Library by making changes to the source code in folder src.
BUILD FAILED. In case the compile process fails, check the output in the console which will give you a closer idea of what went wrong. Errors may have been caused by
Incorrect path settings in the build.properties file.
Error "Javadoc failed". if you are on Windows, make sure you are using a JDK instead of a JRE in order to be able to create the Javadoc for your Library. JRE does not come with the Javadoc application, but it is required to create Libraries from this template.
