Maven 2 Eclipse

Question

使用maven2eclipse插件,问题是零文档.当我在eclipse中右键单击项目时,它给了我一个选择'启用依赖关系管理'我尝试了它但是除了以下控制台输出之外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] 

在尝试弄清楚要做什么之前没有使用过Maven是一个难题.我的印象是,maven应该使用该信息扫描类路径依赖关系来管理项目,但没有这样的运气:(

Maven只管理POM中指定的依赖项(以及任何传递依赖项(即您直接定义的依赖项的依赖项).例如,下面将JUnit作为依赖项添加到测试范围内

<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 - > Add dependency - 这将搜索默认存储库.
