Problem description

There is a mistake in the idea install module. After reading the console information, it is estimated that it is a dependency problem

[ERROR] Failed to execute goal on project 
xxx.yyy.share: Could not resolve dependencies for project 
com.dfl:xxx.yyy.zzz:jar:1.0-SNAPSHOT: 
Failure to find com.xxx:xxx-target:pom:1.0-SNAPSHOT in https://xxxx/snapshot 
was cached in the local repository, 
resolution will not be reattempted until the update interval of spring-snapshots has elapsed or updates are forced -> [Help 1]

Analysis and solution

From the log information, we can see that the zzz module can’t find the jar package, which comes from the target module and can’t be found in the local warehouse or private server.

It is speculated that the jar of private server warehouse is expired or deleted.

So I went to ask the boss, and sure enough, the jar of private server’s warehouse was deleted, so that the boss could deploy it again.

curl: (7) Failed to connect to raw.githubusercontent.com Port 443: several solutions to connection reused?

Preface:
recently, with the release of flutter, most companies begin to use it. But if you want to develop, you need to build a flutter development environment first. You can follow the official website for the installation of flutter. Here we are going to talk about homebrew

curl: (7) Failed to connect to raw.githubusercontent.com Port 443: connection reused note that the suffix is connection reused

My guess: the possible reason for the failure of the installation is that the Xcode environment was not initialized. This is for MAC computers. I found a lot of information on the Internet, and it was said that I could open this website https://raw.githubusercontent.com/Homebrew/install/master/install , I can’t open it
so here’s my solution:

https://www.ipaddress.com/ check out raw.githubusercontent.com corresponding IP address (2) replace the host file of the system note: it's better to copy it before changingthis is actually equivalent to the solution to the problem of network failure. If a web address can be opened on your computer, we will ping it at the terminal (DOS system).
for example:

this is the status of connection. Generally, timeout will be displayed if it is not available. You can try to see if your GitHub is connected（ The same is true for general telecom companies to check network problems, to see if there is packet loss.)

(3) Then install
/bin/bash - C "$(curl - fssl) https://raw.githubusercontent.com/Homebrew/install/master/install.sh ）"
explain: this line/bin/bash – C” $(curl – fssl) https://raw.githubusercontent.com/Homebrew/install/master/install.sh ）”The command is actually the command to install homebrew, You can check the official website address by yourself.

2. Solution 2
execute the following command sudo gem install redis
and then execute /usr/bin/Ruby - e "$(curl - fssl) https://raw.githubusercontent.com/Homebrew/install/master/install )

3. Solution 3
I read other people’s brew_ install.rb The document, which is the website that can’t be opened, is the website https://raw.githubusercontent.com/Homebrew/install/master/install , the corresponding content is brew_ install.rb In fact, many people on the Internet have posted this file, and I have also posted one:
link: Baidu cloud download
password: 1ogr

Enter store brew_ install.rb Execute Ruby brew_ install.rb just follow the prompts to install

4. Solution 4
if the above three methods still have some problems in the installation process, you can try this method.

Step 1: go directly to the GitHub address of homebrew [portal], and pay attention to select the version when downloading. Click branch to switch to tags. Generally, this is the release version
Step 2: after downloading and decompressing, right-click visit, select go to folder…, and enter /usr/local Enter. Just find the homebrew folder in it and replace it with the content you downloaded from GitHub

After that, check whether brew is installed on your Mac, and enter brew

on the terminal to indicate that the installation is completed.
