eclipse - Maven 2 eclipse

Question

使用maven2eclipse插件，问题是零文档。当我在eclipse的“启用依赖关系管理”中右键单击该项目时，它给了我一个选择，但是除了以下控制台输出外，它还给了我一个相当稀疏的POM.xml:

04/05/11 14:57:54 BST: Generating sources /BenCode/pom.xml
04/05/11 14:57:54 BST: Build error for /BenCode/pom.xml; org.apache.maven.plugin.PluginResolutionException: Plugin org.apache.maven.plugins:maven-resources-plugin:2.4.3 or one of its dependencies could not be resolved: Failed to read artifact descriptor for org.apache.maven.plugins:maven-resources-plugin:jar:2.4.3

04/05/11 14:57:54 BST: Failed to determine compiler exclusions, assuming defaults
04/05/11 14:57:54 BST: Refreshing [/BenCode/pom.xml] 

在尝试制定解决方案之前没有使用过Maven就是一个难题。我的印象是，maven应该使用该信息来扫描类路径依赖项来管理项目，但是没有运气:(

Answer 1

Maven将仅管理POM中指定的依赖关系(以及任何传递性依赖关系(即，您直接定义的依赖关系的依赖关系))。
例如。下面将在测试范围内将JUnit添加为依赖项

<dependencies>
    <dependency>
        <groupId>junit</groupId>
        <artifactId>junit</artifactId>
        <version>4.8.2</version>
        <scope>test</scope>
    </dependency>
    <!-- ... -->
</dependencies>

如果右键单击pom.xml，则可以选择Maven->添加依赖项-这将搜索默认存储库。
