Can anyone recommend a good, concise tutorial for Spring? I haven't used it in ages and am supposed to convert a web app to it, so a practical run through of the framework would be great. I think the only non-basic thing Iwould need to do is configure it so that it uses certain classes depending on which profile is used.

Everything is locked down here. We can only install things approved through some group of people and then use the installer provided on our machine. Also they use artifactory internally which is fine except they don't allow outside repos meaning you have to have every dependency requested and then someone manually installs it into artifactory. Bonus: they never add the source or javadoc jars for the library. I honestly have no idea how they got the gradle wrapper placed into the project in the first place since that requires a real gradle install first. I've also wasted way too much time in maven when gradle just works. Heaven forbid you have to deal with any sort of automated pipeline using the maven release plugin.

carry on then posted:What's your thought on using Kotlinscript as the Gradle DSL? It seems a lot better than the Groovy DSL, code completion actually works reliably in IntelliJ. It still hasn't hit 1.0 yet, though it's close (they're up to release candidates). Unfortunately, it doesn't matter for me as my current company is using Play Framework so I'm cursed with using sbt. And we're using the Java API for Play.

BabyFur Denny posted:Why would anyone use Maven over Gradle? I can't get Scala to compile with Gradle. Keep running into dumb errors. Maven was quick and easy for it. On the other hand, Gradle is much better than Maven especially when you can run a bunch of tasks in parallel. Once I got the hang of how to structure everything, I knocked off 70% of average build time for our team. Not a fan of Groovy, but we've been re-writing them in Kotlin. Cached builds are a huge time saver. Especially when you have to do multiple builds in a row because you're a fuckup. geeves fucked around with this message at 04:15 on Aug 18, 2018 |

For testing, I'm trying to set up a data structure that will correspond people to accounts. A person can have multiple accounts, but an account belongs to only one person. I need to be able to query both ways. What would be a good data structure for this? I tried a BidiMap<String, List<String>> from Apache Commons, but I couldn't retrieve the person via one of their accounts, even if the target person had only one account and I did peopleToAccounts.getKey(Arrays.asList("dude's only account")).

BidiMap's docs say it requires a 1:1 relationship (since it's basically a reversible map where either side can be the key and the other the value). So you'd have to look up a person by passing their entire account list as stored - not sure why it didn't work for your single account version though! Maybe the implementation you used doesn't lookup by hashcode etc? Not sure if there's a ready-made collection for it, but I think you basically want to keep a pair of maps - one mapping each person to their collection of accounts (you could use a MultiValuedMap if you want), and then a reverse lookup with a basic map that links each account to its owner, 1:1. Just need to make sure you keep them both synchronised (and synchronized  )This is assuming you want fast lookups both ways, and you can't just store one of those maps and iterate over it to find the opposite thing when you need that baka kaba fucked around with this message at 03:21 on Aug 29, 2018 |

Generally, you should use a Multimap instead of doing it yourself with a map of lists. If you're using Guava, the operation you want is built-in: https://google.github.io/guava/releases/19.0/api/docs/com/google/common/collect/ImmutableMultimap.html#inverse() Not sure if there's an equivalent in apache commons.

yeah that would be great if you can use it. MultiValuedMap is apparently the Commons equivalent but... I haven't used it but it looks weird. Seems like you can check if a value exists somewhere, but that's about it e- maybe it's not that weird, the Guava one looks the same - it just has a convenience function to generate a mirrored copy from an immutable multimap. I thought it was a live inverse view on a mutable one for a minute baka kaba fucked around with this message at 03:27 on Aug 29, 2018 |

I'm looking to run javadoc on this file: https://github.com/ankidroid/Anki-Android/blob/master/api/src/main/java/com/ichi2/anki/FlashCardsContract.java I haven't used java in five years or more so I'm not sure whether I can run something like javadoc.exe myFile.java and have it spit out an myFile.html. The windows examples link on the Javadoc FAQ is a 404. I'm not even sure how to tell if I have the java sdk installed on my machine. java.exe, javaw.exe, and javaws.exe are available in my command prompt, but javac isn't. Any directions to give? (A generous person could also feel free to generate the doc and pastebin it or something if it's a one-step procedure).

If you haven't installed the JDK, it's not installed. The compiler et al aren't put into your PATH by default though, although JAVA_HOME might be (which should point to whichever JDK you're using). That said, if you're using Android Studio, that basically comes with its own JDK. You might want to post in the Android thread too.

I figured it out. Noticing the long-unclicked Eclipse icon on my taskbar, I guessed that some version of the java sdk must exist on the machine. I had earlier tried using windows explorer and the start menu to find javac.exe, but they failed. Of course, it was in the first place I looked (program files (x86)/java/sdk/bin). Eclipse's export javadoc worked out for me. Such pangs of nostalgia at running Eclipse...

So I’m moving into a new position at work where I’m going to be writing mostly Java (coming from a position where I’ve been writing Go almost exclusively for about two years and then perl before that). I haven’t written a line of Java since college when Java 5 was the new hotness. Should I just pick up a copy of Effective Java and go from there? I’m also not super familiar with the intricacies of maven or the tooling around Java in general (not what they were teaching back in Algorithms & Data Structures a decade ago), is there a decent reference/primer for that kind of stuff?

I've had to go back to using Eclipse at work the last few weeks after months of IntelliJ, and it just doesn't compare. It's crashed/frozen a few times, so the loooong startup time is really noticeable. The whole "perspective" thing is kind of annoying, especially when debugging and fixing code. It's pretty ugly.

Honestly, if there is one thing I wish they could go back and revisit a decision that was made early on in Eclipse's life, it's perspectives. It probably seemed a good idea at the time, but it just hinders instead of helps most of the time as far as I am concerned. I feel the way it's done in Idea works a lot smoother, esp. with debug. ivantod fucked around with this message at 19:42 on Sep 3, 2018 |

Give it a while. Keep looking up shortcuts, eventually you'll become a powerful intellij keyboard warrior. If it helps, I'm p sure there's a built in way to set yourself up with eclipse keybinds
