vscode run spring boot - The newly created daemon process has a different context than expected

针对问题

先说下本机器默认java版本

$ java -version
java version "1.8.0_121"
Java(TM) SE Runtime Environment (build 1.8.0_121-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.121-b13, mixed mode)

在使用vscode创建spring boot项目的时候，遇到一个问题，就是vscode会提示你

“Java 11 or more recent is required to run. Please download and install a recent JDK”

我以为应该要用java 11

于是我就用brew 安装了java 11，安装后的信息如下

$ brew info openjdk@11
openjdk@11: stable 11.0.8 (bottled) [keg-only]
Development kit for the Java programming language

Build: autoconf ✔
==> Caveats
For the system Java wrappers to find this JDK, symlink it with
  sudo ln -sfn /usr/local/opt/openjdk@11/libexec/openjdk.jdk /Library/Java/JavaVirtualMachines/openjdk-11.jdk

openjdk@11 is keg-only, which means it was not symlinked into /usr/local,
because this is an alternate version of another formula.

If you need to have openjdk@11 first in your PATH run:
  echo 'export PATH="/usr/local/opt/openjdk@11/bin:$PATH"' >> ~/.zshrc

For compilers to find openjdk@11 you may need to set:
  export CPPFLAGS="-I/usr/local/opt/openjdk@11/include"

install-on-request: 18,766 (30 days), 30,811 (90 days), 53,043 (365 days)
build-error: 0 (30 days)

然后我需要用到java 11在vscode中，在setting加入如下参数配置

"java.home": "/usr/local/Cellar/openjdk@11/11.0.8/"

然后运行sping boot项目，遇到了类似如下的问题

The newly created daemon process has a different context than expected.
It won’t be possible to reconnect to this daemon. Context mismatch:
Java home is different.
Wanted: DefaultDaemonContext[…]
Actual: DefaultDaemonContext[…]

经过google搜索一大堆的那个什么ide的问题

主要原因在这里

https://github.com/redhat-developer/vscode-java/wiki/JDK-Requirements#java.configuration.runtimes

只需要将

"java.home": "/usr/local/Cellar/openjdk@11/11.0.8/",

替换并修改为如下

"java.home": "/usr/local/Cellar/openjdk@11/11.0.8/libexec/openjdk.jdk/Contents/Home/",
"java.configuration.runtimes": [
    {
        "name": "JavaSE-11",
        "path": "/usr/local/Cellar/openjdk@11/11.0.8/libexec/openjdk.jdk/Contents/Home/"
    },
]

再次运行，问题解决，其实github上的一篇文章写的比较详细
