Draft: Upgrade gradle-wrapper to version 5.0
Closes #63
This PR upgrades gradle-wrapper version to 5.0, allowing the project to be built using JDK 11.
It also removes deprecated built-in task overwrite. Gradle-wrrapper version should now be maintained only in ./gradle/wrapper/gradle-wrapper.properties
There are a lot more issues than I thought there would be, as other plugins/dependencies & even html tags in documentations have become deprecated.
@PL4typus Thanks for you P/R, I'm just figuring out myself the issue.
I'm currently adding support for php8.0 in soluble-japha and pjbserver-tools
- https://github.com/belgattitude/soluble-japha/pull/60 (fail https://travis-ci.org/github/belgattitude/soluble-japha/jobs/767570065)
- https://github.com/belgattitude/pjbserver-tools/pull/10
Any chance you would work more on that ?
PS/ did some work here: https://github.com/belgattitude/php-java-bridge/pull/65
