Question

我目前正在尝试构建一个具有多个依赖项的Java项目。我已将其创建为Maven Web应用程序，并添加了所有必需的依赖项。然而，进口没有得到解决。

在下面的链接中，我附上了我的Netbeans的屏幕截图，其中在右侧面板中，可以看到导入错误。在左侧面板中，我突出显示了我添加的库。谁能告诉我为什么会这样？任何帮助将非常感谢。谢谢:)）

Answer 1

可能是因为您向我们展示的文件位于源包中（solr-common * sources * jar）（请注意，而不是指向扩展名为.java的文件，而不是.class），而不是在编译库中。将已编译的库包含到您的项目中。需要查看pom文件以提供更详细的答案

在看到.pom文件后：你应该改变

<dependency>
    <groupId>solr</groupId>
    <artifactId>solr-common-1.3.0-sources</artifactId>
    <version>1.3.0</version>
</dependency>

到

<dependency>
    <groupId>solr</groupId>
    <artifactId>solr-common</artifactId>
    <version>1.3.0</version>
</dependency>
