Stop using libraries for standard library stuff

Map.computeIfAbsent(__ -> new <Collection>()).add(...)
Multimap 😄
Collection can be any collection you like
And Map shoudl be defined as
Map<K, Collection<V>>
Since 11 I don't use Guava anymore
If you're making a library to do something that might be useful to other people, please do remove as many dependencies as you can. Especially all the utility stuff like guava or http client libraries etc
Depends on how hard you're set on targeting Java 8 ofcUnknown User•15mo ago

well, just stick with junit-jupiter
junit junit is the old version
so that can be removed
And the default seems to be trending towards slf4j, so maybe use slf4j-api instead of log4j-api

jackson is probably a good default choice, are you writing a http client library? Like an SDK of sorts?

ah, because there's jackson-datatype-jdk8 if you need jdk8 types

Set of support modules for Java 8 datatypes (Optionals, date/time) and features (parameter names) - GitHub - FasterXML/jackson-modules-java8: Set of support modules for Java 8 datatypes (Optionals,...
You don't need them if you don't use those types
But I come across http client sdks that still use java util Date sometimes 🙂

If you actually looked at the screenshot you'd have seen he uses log4j-API, which isn't an implementation, hence why I suggested to use slf4j-api
Pretty sure you don't have to fully specify the resources plugin. Theres a shorthand if you just want to enable filtering
OK, so much of this is wrong:
log4j is for logging stuff urself
org.apache.logging.log4j:log4j-core is the actual implementation
they are not interchangable..... slf4j is an protocol
org.apache.logging.log4j:log4j-api, which he's using is as well
and log4j is an implementation (of slf4j - btw) .....No it isn't, to bridge those two you need either
org.apache.logging.log4j:log4j-slf4j-impl if you're using log4j as your implementation, or org.slf4j:log4j-over-slf4j if using slf4j, which would either be slf4j-simple or logback classic💤 Post marked as dormant
