我正在尝试用 maven 编译一些 java 类来生成一个独立的可执行 jar 文件

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

      <execution>
        <id>make-assembly</id> <!-- this is used for inheritance merges -->

          <goals>
            <goal>single</goal>
          </goals>
      </execution>
    </executions>
  </plugin>
</plugins>

我想生成一个独立的 jar 文件，就像这里解释的 https://maven.apache.org/plugins/maven-assembly-plugin/usage.html

我得到的错误是：

我在Haskell中编写了下面的函数,我不太清楚为什么它不适用于懒惰的评估.

infFib :: [Integer]
infFib = infFib' []
    where 
        infFib' [] = infFib' [0,1]
        infFib' (xs) = infFib' (xs ++ [(foldr (\a b -> a+b) 0 (take 2 (reverse xs)))])
