JDK

在 m1 macbook 上安装 jdk 相对会有更多的麻烦，因为 m1 的 cpu 架构不再时传统的 x86_64 ，而是 aarch64 (arm64)。

安装 JAVA SDK （for M1）

暂时使用 jdk 11，在 m1 上需要安装多个版本：

zuul jdk : arm64 版本，作为原生版本使用
openjdk 11: x64 版本
graalvm 11: x64 版本，学习 quarks / spring native 使用。（备注：graalvm 目前还没有 m1 原生支持）

zulu 11.0.14 (arm64)

zulu 是对 macos + arm64 支持比较好的 jdk，推荐作为 m1 的原生 java sdk：

$ sdk install java 11.0.14-zulu

Downloading: java 11.0.14-zulu

Do you want java 11.0.14-zulu to be set as default? (Y/n): y

Setting java 11.0.14-zulu as default.

但特别注意，如果开启了 rosetta2 兼容模式，则会安装 x86_64 版本，而不是我们期望的 arm64 版本。

删除已经安装的 x86_64 版本的zulu jdk，特别注意要删除已经下载的 sdk 缓存文件，不然下次安装时会报告本地已经有文件而跳过下载过程。由于本地的是之前下载的 x86_64 版本，因此会导致无法安装 arm64 版本，必须删除本地缓存目录 ~/.sdkman/archives 下对应的安装文件：

# 删除已经安装的 x86_64 版本的zulu jdk
$ sdk uninstall java 11.0.14-zulu   

# 删除已经下载的 java-11.0.14-zulu.zip 文件
$ ls ~/.sdkman/archives
java-11.0.14-zulu.zip   java-11.0.2-open.zip    java-20.3.5.r11-grl.zip maven-3.8.5.zip
$ rm ~/.sdkman/archives/java-11.0.14-zulu.zip

备注：下载的安装文件不区分是否是 rosetta2 兼容模式，x86_64 和 arm64 下安装文件名是相同的。

如果要安装 arm64 版本，则需要关闭 rosetta2 兼容模式。vi ~/.sdkman/etc/config:

sdkman_rosetta2_compatible=true	# 修改这里为 false 关闭 rosetta2 兼容模式

修改后在当前终端中执行下面的命令立即更新：

source "/Users/sky/.sdkman/bin/sdkman-init.sh"

再次安装即可：

sdk install java 11.0.14-zulu  

Downloading: java 11.0.14-zulu

Setting java 11.0.14-zulu as default.

还是需要执行下面的命令立即更新：

然后检查安装后的 java 设置：

$ which java                                    
/Users/sky/.sdkman/candidates/java/current/bin/java

Setting java 11.0.2-open as default.

安装完成之后，可以通过 sdk current 命令看到当前正在使用的 sdk 和版本：

$ sdk current  

Using:

java: 11.0.2-open

检查一下当前的 java 设置：

$ which java
/Users/sky/.sdkman/candidates/java/current/bin/java

$ java --version
openjdk 11.0.2 2019-01-15
OpenJDK Runtime Environment 18.9 (build 11.0.2+9)
OpenJDK 64-Bit Server VM 18.9 (build 11.0.2+9, mixed mode)

$ env | grep JAVA_HOME
JAVA_HOME=/Users/sky/.sdkman/candidates/java/current

查看一下本地文件的目录结构就清楚了：

$ ls -l /Users/sky/.sdkman/candidates/java/
total 0
drwxr-xr-x   9 sky  staff  288  1 18  2019 11.0.2-open

graalvm 20.3.5.r11 (x86_64)

为了使用 quarkus，安装 graalvm 20 版本，由于 graalvm 暂时没有 m1 可用的 arm64 版本，因此只能安装 x86_64 版本：

sdk install java 20.3.5.r11-grl

检查安装后的 java 设置：

$ which java                     
/Users/sky/.sdkman/candidates/java/20.3.5.r11-grl/bin/java

$ java --version

Installing: maven 3.8.5

Setting maven 3.8.5 as default.

检查 maven 的安装， mvn 没有 arch 的差异，完全取决于当前 maven 使用的 java sdk。因此使用不同 java sdk 时的输出是不一样的。

查看当前安装好的 java sdk ：

$ sdk list java | grep installed

               |     | 20.3.5.r11   | grl     | installed  | 20.3.5.r11-grl      
               |     | 11.0.2       | open    | installed  | 11.0.2-open         
               | >>> | 11.0.14      | zulu    | installed  | 11.0.14-zulu

对比 mvn --version 在不同 java sdk 下的输出。在 openjdk x86_64 下：

$ sdk use java 11.0.2-open
$ mvn --version
Apache Maven 3.8.5 (3599d3414f046de2324203b78ddcf9b5e4388aa0)
Maven home: /Users/sky/.sdkman/candidates/maven/current

$ env | grep MAVEN_HOME
MAVEN_HOME=/Users/sky/.sdkman/candidates/maven/current

在 graalvm x86_64 下：

$ sdk use java 20.3.5.r11-grl
$ mvn --version
Apache Maven 3.8.5 (3599d3414f046de2324203b78ddcf9b5e4388aa0)

Default locale: zh_CN_#Hans, platform encoding: UTF-8
OS name: "mac os x", version: "12.3", arch: "x86_64", family: "mac"

在 zulu arm64 下：

$ sdk use java 11.0.14-zulu
$ mvn --version
Apache Maven 3.8.5 (3599d3414f046de2324203b78ddcf9b5e4388aa0)
Maven home: /Users/sky/.sdkman/candidates/maven/current
Java version: 11.0.14, vendor: Azul Systems, Inc., runtime: /Users/sky/.sdkman/candidates/java/11.0.14-zulu/zulu-11.jdk/Contents/Home
Default locale: zh_CN_#Hans, platform encoding: UTF-8
OS name: "mac os x", version: "12.3", arch: "aarch64", family: "mac"

注意： zulu arm64 下 maven 的输出中 arch 终于改为 “aarch64” ，而不是 “x86_64”。

这个方法也可以用来快速检查当前 java sdk 是 “x86_64” 还是 “aarch64” （arm64）版本。

自动切换JDK

通常使用场景时默认使用一个 jdk，然后在某些目录下需要使用其他的 jdk。例如我在 m1 macbook 下默认使用 aarch64 （arm64）的 zulu jdk，但在某些特殊项目如 dapr 的 java-sdk 项目下，必须使用 x86_64 的 openjdk。

sdkman 提供在进入某些项目或目录时自动切换 sdk 的功能。

vi ~/.sdkman/etc/config 打开 sdkman 的配置文件，设置 sdkman_auto_env 为true:

sdkman_auto_env=true

source "~/.sdkman/bin/sdkman-init.sh" 让配置生效。然后：

# 用 mvn --version 命令查看 arch，默认用的是 zulu jdk，因此是 aarch64
mvn --version
OS name: "mac os x", version: "12.3", arch: "aarch64", family: "mac"

# 进入需要设置的目录
$ cd word/code/dapr/java-sdk

# 切换到 x86-64 的 openjdk 
$ sdk use java 11.0.2-open
# 用 mvn --version 命令查看 arch，此时是 x86_64
$ mvn --version
OS name: "mac os x", version: "10.16", arch: "x86_64", family: "mac"

# 初始化sdk env，sdkman 会记录下当前使用的 jdk 到当前目录下的 .sdkmanrc 文件
$ sdk env init
.sdkmanrc created.

vi .sdkmanrc 查看内容：

# Enable auto-env through the sdkman_auto_env config
# Add key=value pairs of SDKs to use below
java=11.0.2-open

在终端中尝试进入和退出项目所在目录：

$ cd ..      
Restored java version to 11.0.14-zulu (default)

$ cd java-sdk 
Using java version 11.0.2-open in this shell.

# 在子目录中跳转时不会触发自动切换的，也就是目录下的所有子目录都将维持这个sdk设置
$ cd sdk-autogen

5 - JDK Mission Control

JDK Mission Control

介绍

https://www.oracle.com/java/technologies/jdk-mission-control.html

在 zule jdk上，使用的是 zulu mission control：

https://www.azul.com/products/components/zulu-mission-control/

支持

安装

使用 sdkman 安装

默认的 jmc 8.1.1.51-zulu 版本不支持 m1：

$ sdk install jmc   

Stop! jmc 8.1.1.51-zulu is not available. Possible causes:
 * 8.1.1.51-zulu is an invalid version
 * jmc binaries are incompatible with your platform
 * jmc has not been released yet

Tip: see all available versions for your platform:

  $ sdk list jmc

用 sdk list jmc 命令查看发现有 8.1.1.57-zulu 版本：

$ sdk list jmc                 

================================================================================
Available Jmc Versions
================================================================================
 >   8.1.1.57-zulu

用这个 8.1.1.57-zulu 版本继续安装：

$ sdk install jmc 8.1.1.57-zulu

Downloading: jmc 8.1.1.57-zulu

In progress...

Repackaging JMC zulu 8.1.1.57-zulu...

Done repackaging...

Installing: jmc 8.1.1.57-zulu
mv: /Users/sky/.sdkman/candidates/jmc/8.1.1.57-zulu is not a directory
Done installing!


Setting jmc 8.1.1.57-zulu as default.

安装时似乎出错了，ls ~/.sdkman/candidates/jmc 检查 .sdkman 目录下发现安装的确出错了：

$ ls -l ~/.sdkman/candidates/jmc
lrwxr-xr-x  1 sky  staff   13  3 21 08:18 current -> 8.1.1.57-zulu

再安装一次：

$ sdk install jmc 8.1.1.57-zulu

Found a previously downloaded jmc 8.1.1.57-zulu archive. Not downloading it again...


Installing: jmc 8.1.1.57-zulu
Done installing!

Do you want jmc 8.1.1.57-zulu to be set as default? (Y/n): Y

Setting jmc 8.1.1.57-zulu as default.

这次对了：

$ ls -l ~/.sdkman/candidates/jmc
drwxr-xr-x  6 sky  staff  192  3 21 07:47 8.1.1.57-zulu
lrwxr-xr-x  1 sky  staff   13  3 21 08:18 current -> 8.1.1.57-zulu

但执行时报错：

$ jmc version
The operation couldn’t be completed. Unable to locate a Java Runtime that supports jmc.
Please visit http://www.java.com for information on installing Java.

$ which jmc
/usr/bin/jmc

Jmc 指向的是 /usr/bin/jmc，这个应该是我之前手工安装 zule jdk 时复制过去的文件。

sudo rm -rf /usr/bin/jmc
rm: /usr/bin/jmc: Operation not permitted
