Question

在使用Maven的Java项目中，我为JxBrowser添加库。

程序编译正常 - 没有错误，但是当我尝试在Intelij IDEA中运行它时会返回错误。

它显示何时尝试创建BrowserView对象（它是lib包com.teamdev.jxbrowser.chromium.swing中的一个类）并返回两个错误NoClassDefFoundError和CLassNotFoundException，完整消息如下所示：

我该如何解决？

当我键入BrowserView browserView = new BrowserView()时，它没有突出显示，这意味着在项目资源中找到了lib。

pom.xml包含：

<dependencies>
    <dependency>
        <groupId>com.teamdev.jxbrowser</groupId>
        <artifactId>jxbrowser-mac</artifactId>
        <version>6.11.1</version>
    </dependency>
</dependencies>

<repositories>
    <repository>
        <id>com.teamdev.jxbrowser</id>
        <url>http://maven.teamdev.com/repository/products</url>
    </repository>
</repositories>

编译项目时，库成功下载，没有错误。

修改

我在OS X系统和IntelliJ IDEA上工作。我在模块设置 - Dependencies选项卡中添加了license.jar文件，询问我选择了哪种类型＆＃34;类＆＃34;它也被设置为＆＃34;编译＆＃34;

编辑2

我检查了System.getProperty("java.class.path")并且没有.jar文件给JxBrowser ......但为什么呢？在模块依赖项中设置时

Answer 1

<强>解决

在JxBrowser安装指南（JxBrowser Installation）中，没有关于添加依赖关系的信息，如下所示

<dependency>
    <groupId>com.teamdev.jxbrowser</groupId>
    <artifactId>jxbrowser</artifactId>
    <version>${jxbrowser.version}</version>
</dependency>

仅适用于不同的系统（如Windows，Mac，Linux），但不适用于主库。
