我创建了两个Maven项目。下面是两个项目的POM文件;
1.核心库-
<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">
<modelVersion>4.0.0</modelVersion>
<groupId>com.demo</groupId>
<artifactId>core-library</artifactId>
<version>0.0.1-SNAPSHOT</version>
<name>Core</name>

1.实用程序库-
<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">
<modelVersion>4.0.0</modelVersion>
<groupId>com.demo</groupId>
<artifactId>utility-library</artifactId>

现在核心库有一些外部依赖关系,例如。反射:反射等。因此,我的期望是,当我将核心库添加到实用程序库时,这些外部依赖关系应该自动添加到实用程序库的依赖关系树中。
但实际上,这些嵌套的依赖关系并没有被包含在实用程序库的依赖关系树中。
下面是我在实用程序库上运行mvn dependency:tree
时的输出
--- maven-dependency-plugin:2.8:tree (default-cli) @ utility-library ---
[INFO] com.demo:utility-library:jar:0.0.1-SNAPSHOT
[INFO] +- com.demo:core-library:jar:0.0.1-SNAPSHOT:compile
INFO] ------------------------------------------------------------------------
[INFO] BUILD SUCCESS

我试过从this堆栈溢出问题的解决方案,但问题还没有解决。
有人能帮帮我吗?
P.S. -我必须实现这个嵌套的依赖包含而不创建一个胖/shaded/uber jar,因为它增加了实际的jar大小,我还想进一步使用utility-library作为一个maven依赖在其他项目。
**UPDATE:**当我尝试构建带有-X(enable debug logs)标志的utility-library时,我得到了以下错误:
[WARNING] The POM for com.demo:core-library:jar:0.0.1-SNAPSHOT is invalid, transitive dependencies (if any) will not be available: 3 problems were encountered while building the effective model for com.demo:core-library:0.0.1-SNAPSHOT

你的POM看起来很正确。
reflections
是一个传递依赖,应该由Maven自动绘制。如果你看不见它,请看
mvn dependency:tree
。它应该列在那里。也许你的IDE在显示废话。
