· 3分钟阅读

环境​

  • Windows 10
  • Idea 2023.2.2
❯ java -version
openjdk version "11.0.19" 2023-04-18
OpenJDK Runtime Environment GraalVM CE 22.3.2 (build 11.0.19+7-jvmci-22.3-b18)
OpenJDK 64-Bit Server VM GraalVM CE 22.3.2 (build 11.0.19+7-jvmci-22.3-b18, mixed mode, sharing)

WARNING: Windows Developer Mode is not enabled on your system, this is necessary

0.110.1

安装JBang​

scoop install jbang

HelloWorld​

新建​

❯ jbang init Hello.java
[jbang] File initialized. You can now run it with 'jbang Hello.java' or edit it using 'jbang edit --open=[editor] Hello.java' where [editor] is your editor or IDE, e.g. 'codium'. If your IDE supports JBang, you can edit the directory instead: 'jbang edit . 'Hello.java. See https://jbang.dev/ide

运行​

❯ jbang .\Hello.java
Hello World

Cli​

新建​

❯ jbang init Cli.java
[jbang] File initialized. You can now run it with 'jbang Cli.java' or edit it using 'jbang edit --open=[editor] Cli.java' where [editor] is your editor or IDE, e.g. 'idea'. If your IDE supports JBang, you can edit the directory instead: 'jbang edit . 'Cli.java. See https://jbang.dev/ide

运行​

❯ jbang .\Cli.java Tom
[jbang] Building jar for Cli.java...
Hello Tom

编辑​

使用Idea​

❯ jbang edit --open=idea .
[jbang] Assuming your editor have JBang support installed. See https://jbang.dev/ide
[jbang] If you prefer to open in a sandbox run with `jbang edit -b` instead.
[jbang] Starting 'idea'.If you want to make this the default, run 'jbang config set edit.open idea'

打开之后发现，并没有识别出依赖的包，红彤彤的一片：

可能是插件用得不对，一顿折腾无果之后，只能另寻他路曲线救国了；

把当前目录当作一个IDEA的项目来看，添加好相关的依赖就可以：

额，现在好像和一个普通的项目也没什么区别了，只是更方便运行发布而已。

proxy​

参考这里配置，主要有三步

  1. 设置system proxy，配置两个环境变量就可以：
# 此处用的本地clash
$env:http_proxy=http://127.0.0.1:7890
$env:https_proxy=http://127.0.0.1:7890
  1. 设置Java的JAVA_TOOL_OPTIONS环境变量：
$env:JAVA_TOOL_OPTIONS="-Dhttp.proxyHost=127.0.0.1 -Dhttp.proxyPort=7890 -Dhttps.proxyHost=127.0.0.1 -Dhttps.proxyPort=7890"
  1. 设置maven：
<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0
                              http://maven.apache.org/xsd/settings-1.0.0.xsd">
    <proxies>
        <!-- For HTTP -->
        <proxy>
            <id>http-proxy</id>
            <active>true</active>
            <protocol>http</protocol>
            <host>127.0.0.1</host>
            <port>7890</port>
        </proxy>
        <!-- For HTTPS -->
        <proxy>
            <id>https-proxy</id>
            <active>true</active>
            <protocol>https</protocol>
            <host>127.0.0.1</host>
            <port>7890</port>
        </proxy>
    </proxies>
</settings>

如果只是运行命令行的话，应该只需要前面两步就可以了。
