mvn依赖项:树在简单的项目上失败
mvn依赖项:树在简单的项目上失败
提问于 2015-03-03 15:20:15
我有一个相当复杂的项目(大约100个模块)，我想在这个项目上运行mvn dependency:tree。它失败了，抱怨它无法解决依赖关系。否则该项目会编译得很好。因此，我创建了一个最基本的项目，但它仍然失败，同样的错误。显然，要么我做了一些非常基本的错误，否则maven依赖插件还没有被任何人使用。以下是三个POMs im by测试项目：
pom.xml：
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<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.example</groupId>
<artifactId>root</artifactId>
<version>1.0.0-SNAPSHOT</version>
<packaging>pom</packaging>
<modules>
<module>foo</module>
<module>bar</module>
</modules>
</project>foo/pu.xml：
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<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.example</groupId>
<artifactId>foo</artifactId>
<version>1.0.0-SNAPSHOT</version>
<packaging>jar</packaging>
</project>bar/pu.xml：
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<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.example</groupId>
<artifactId>bar</artifactId>
<version>1.0.0-SNAPSHOT</version>
<packaging>jar</packaging>
<dependencies>
<dependency>
<groupId>com.example</groupId>
<artifactId>foo</artifactId>
<version>1.0.0-SNAPSHOT</version>
</dependency>
</dependencies>
</project>然后，在顶层目录中发出以下命令mvn dependency:tree，并获得以下输出：

对我来说，这些都没有用。我的maven-enforcer-plugin依赖版本被设置为3.0.0，但将其更改为3.0.0-M3对我起了作用。
