[JAVA] Try to quit Eclipse and switch to Visual Studio Code

Introduction

My work mainly deals with Java. And I usually use Eclipse as an IDE. Project configuration management is maven.

But recently I started studying golang and started thinking "I wonder if I can unify the IDE ...", and Visual Studio Code is good, right? It is a story that I challenged. At the company, the front end is Angular and uses Visaul Studio Code, and if this can be done, it can be unified! There isn't much merit, though! I felt like.

Maybe it's convenient if you haven't mastered it yet or actually add another plugin! There may be something like that. It would be greatly appreciated if you could comment.

-** It can be used enough for personal development! (Rather, I want to use it) ** --Eclipse is recommended for high-spec PCs for projects with 100 people. VS Code for low specs.
Basic maven project Since it is a rule that anything works, what do you recommend? level.
IntelliJ IDEA is popular, but there aren't many people around it who can use it. ――It looks good with Spring Boot!

○ ・ ・ ・ Can be used enough! △ ・ ・ ・ Some dissatisfaction. × ・ ・ ・ Cannot be used.

• 1: If multiple candidates are found, some parts may be a little difficult to use. (Click to select the problem area)
• 2: Probably there is no function to open the source of the target external library from the code displayed in stacktrace.
• 3: There is no GUI like egit. It doesn't matter if you can use commands.
• 4: It seems likely, but there is no such thing as creating a new class. I want a template function like Eclipse.
• 5: Mmm ... I feel like I can't easily check conflicts. Well, I rarely check it.

Functions expected from IDE (editor) in the first place

If I can achieve this, I'm wondering if Visual Studio Code is fine. The ones listed above have the highest priority.

1. Code storage. I hate typing.
2. Import storage. I don't write an import statement.
3. Code format. I cry if you don't format it.
4. Display of compilation error location.
5. Style check. It's a pain if you don't check the rules while coding.
6. Debugging function. It is difficult to debug unless you click the class displayed in stacktrace and display the corresponding part.
7. Cooperation with git repository (individual = github, company = gitlab).
8. Source template generation. I don't want to enter class comments or file headers.
9. Dependency display in pom.xml. dependency: tree I don't want to enter it and want to see it in the GUI.

Visual Studio Code setup

It was added as an add-on. See the information below for setup. https://code.visualstudio.com/docs/languages/java

I will use Lombok, so I will put it in.

https://marketplace.visualstudio.com/items?itemName=Pivotal.vscode-spring-boot

It is a convenient extension related to Spring Boot setting storage and endpoints.

It didn't work

Endpoint display during Debug of Spring Boot Tools

The endpoint will be displayed. But ... Even if you select an endpoint from there, an error will occur as shown below.

Hmm. The browser should open, but ... I gave up the investigation because there was no error anywhere. https://github.com/spring-projects/sts4/blob/master/CONTRIBUTING.adoc I thought I'd ask a question on stack over flow, --There is no spring-tools-4 tag yet. --You can't create a new tag with the account you just created With that feeling ... https://stackoverflow.com/questions/52128210/vscode-not-work-quick-access-for-running-apps-with-spring-boot-tools This happened: disappointed_relieved: Whether or not the English is really understandable ...!

Let's try (expect) from now on

Java with Kubernetes in VS Code https://code.visualstudio.com/docs/java/java-kubernetes Oh? Can it work with Kubernetes? Well, honestly, I don't know the merit of running it with Kubernetes in a local environment, but it looks interesting!

VS Live Share/VS Live Share Audio

Functions learned from Yuru Web Study Group @ Sapporo # 1. Can this be used for technical support of contractors? I think it's amazing. It seems to be better than slack than QA tickets.
