Hi, Try updating your jdk... also maven itself.
But you can also create a (new) ordinary maven project, use the example code (PrintTextLocations) you mentioned as main, and use pdfbox dependencies in the pom without having to build the whole project.

Downloaded PDFBox 2.0.21 source code from the website to an Ubuntu Server LTS 18.04.2 server, extracted it, ran 'mvn clean install', and got errors. "Insanity is doing the same thing over and over again and expecting a different result" but in this case, repeating the same, exact command eventually started pulling down packages from Maven. First, it was failure to connect to Maven sources which magically corrected themselves after a while but still broke at least two more times. Re-running the same 'mvn clean install' command repeatedly eventually "fixed" the problem. Then I ran into this: [INFO] --- maven-compiler-plugin:3.6.0:compile (default-compile) @ fontbox --- [INFO] Changes detected - recompiling the module!

Tried various things without any difference in the outcome. All I really want is the precompiled 'examples' JARs. Specifically, the 'examples/util/PrintTextLocations' example because the precompiled pdfbox CLI tool doesn't have an option to dump character location information within the ExtractText option but the PrintTextLocations example code does! I just need to be able to parse character locations from stdin in my language of choice and I don't want to try parsing PDFs myself if there are already tools that can do that.
