为什么 maven 无法为这个项目构建

Question

我在 Ubuntu 中使用 maven 3.6。我的 pom.xml:-

    <?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

            </plugin>
        </plugins>
    </build>

</project>

我得到错误：-

Error:(7,8) java: cannot access org.springframework.cloud.function.context.AbstractSpringFunctionAdapterInitializer

这里有什么问题？我该如何解决？

我尝试了各种新旧版本的 spring-cloud-function-adapter-aws。我设法通过以下版本编译。

    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-function-adapter-aws</artifactId>
        <version>1.0.1.RELEASE</version>
    </dependency>
