azure-函数-maven-plugin类路径中缺少的最终jar库

Question

我正在尝试从我的本地机器部署Java函数应用程序。我的技术堆是法洛斯，

Azure Function App OS: Linux
Azure Functions Core Tools (2.0.3)
Springboot 2.6.3
spring-boot-maven-plugin 2.6.3
azure-functions-maven-plugin 1.14.3
azure-functions-java-library 1.4.2
spring-cloud-function-adapter-azure 3.2.1

这是我的pom.xml

Function从IntellIJ IDEA本地运行良好，并通过mvn azure-functions:run命令运行。

当我使用java命令java -jar <>运行jar时，它失败了，没有类定义找到错误。

mvn azure-functions:deploy在没有任何问题的情况下成功，并且能够看到在azure上创建的函数，但是当我触发函数时，它会因为500个内部错误而失败。

我怀疑由于外部依赖关系没有添加到jar的类路径，函数在azure中失败了。从堆栈溢出中，我发现了类似的问题here，建议使用maven程序集插件，但是我的问题是，当我使用springboot插件时，为什么要使用组装插件呢？

Answer 1

最后，通过windows上的MSI安装程序，解决了安装Azure函数Core 4.x版本后的问题。

https://learn.microsoft.com/en-us/azure/azure-functions/functions-run-local?tabs=v4%2Cwindows%2Ccsharp%2Cportal%2Cbash#v2

当函数触发时，它看起来像是/lib文件夹在暂存目录下的引用，它不需要弹靴fat jar。
