Apache Ant VS Quartz

-- https://ant.apache.org/

I will not suggest truly old-school Java programming. When I started in Java, we built Java classes with the javac command. This led to writing shell scripts to build complex projects and finally, Makefiles using the Unix and Windows commands make and nmake respectively. I remember being thrilled when the Ant utility came out and we had a pure Java build tool.

Didn't know that people still use Ant for building their source code.

A build system is a program that orchestrates the execution of underlying tools such as compilers, code generators, test runners, linters and so on. Examples of build systems include the venerable Make, the JVM-centric Ant, Maven and Gradle, and newer systems such as Pants and Bazel (full disclosure: I am one of the maintainers of Pants).

You are missing a dependency: antlr. You have ant instead, which is something completely different.

make has many detractors, but I've shipped some fairly large projects using nothing but it as the build system. Once you've settled on a particular implementation of make, you can get a lot done with it. The pain comes in when you want to do even modestly interesting things and you need it to work on both GNU make and SysV (or BSD) make. Its syntax also speaks loudly as to the era which it's from, but the same could be (unfavorably) said of things like Visual Studio project files and Ant.

In java we have found Quartz( Quartz) , Job Runr(Jobrunr) and db-scheduler(db-scheduler) and need to evaluate these for our use case.

Im mit sit what you mean by "not supported", you sure can run MongoDB on Kubernetes. Maybe I'm way off, are you saying that you can't use Quartz (this one: http://www.quartz-scheduler.org/ ?) because it doesn't natively allow you to load from MongoDB and.therefor you can't use it?

Uh this class is even worse, SDF is not a thread safe date formatter, so it never should be `final static`. `releaseDate` and `new Date()` will be ignorant of summer/winter time changes. For such scheduling one should use Quartz https://www.quartz-scheduler.org/

Have a look at http://www.quartz-scheduler.org/ If you're using Java

Long time I used http://www.quartz-scheduler.org which worked nicely, I wonder why Scala does not seem to have something standard for this.

Quartz Scheduler

We have a separate service for running cron jobs. It uses Quartz (http://www.quartz-scheduler.org/) and it has a REST API that we use to submit new jobs. It's easy to set up and all you need is a database. You definitely need a database in order to synchronize across different containers.
