Maven - 即使依赖路径正确也是编译错误

Question

我手动在位于.m2 / repository的Maven存储库下添加了一个jar文件。

然后我还编辑了项目的pom.xml文件

jar文件也出现在Maven Dependencies

下

但是，当我在源文件的根目录下执行此命令mvn assembly:assembly -DdescriptorId=jar-with-dependencies package时，我会收到此错误：

我不明白为什么会这样。

-----更新-----

我也尝试通过命令添加jar：

mvn install:install-file -Dfile=/Users/jun/Desktop/Projects/WowLamp/alexa-skills-kit-java-master/samples/lib/java-json.jar -DgroupId=json.java -DartifactId=java-json -Dversion=1.0 -Dpackaging=jar -DgeneratePom=true

这是安装后jar文件的层次结构：

但仍然会发生同样的错误。

您需要使用以下命令安装jar，而不是手动将其复制到存储库中。

mvn install:install-file -Dfile=java-json-1.0.jar -DgroupId=json.java \
-DartifactId=java-json -Dversion=1.0 -Dpackaging=jar

您可以咨询专家doc了解更多详情。
