如何使用 Maven 为 Micronaut 创建可执行 jar 文件?
How to create executable jar file for Micronaut using maven?
我正在尝试使用 maven
.
为 Micronaut 框架构建并 运行 一个简单的可执行 jar
文件
我的工作:
- 运行
mvn clean package
- 尝试运行申请
java -jar target/simple_server-0.1.jar
- 获取下一个异常:
Error: Could not find or load main class com.github.volodya_lombrozo.Application
Caused by: java.lang.ClassNotFoundException: com.github.volodya_lombrozo.Application
这里的主要问题是如何正确使用 maven
构建和 运行 Micronaut
应用程序?也许我错过了什么?
这是我的 pom.xml
文件
