I just tried using picocli in one of my android projects (android 9). See here for more information about picocli. I tried picocli before in a local project (just with a main method, not using android) and it worked well.
But then I adapted the code to get it works in android app, and a got an exception inside picocli when processing some regex, and I made some tests to figure out what was going on. When I try to run this code :
String test = "test";
test.replaceAll("\\$\\{COMMAND-NAME}", "string replacement");
- If it is a classic java app : no problem.
- If it is inside android app : This exception occurs :
