带有maven异常的Java SWT线程"main“java.lang.NoClassDefFoundError: org/eclipse/swt/widgets/复合

Question

我正在尝试创建一个独立的应用程序与java，maven和swt。它是构建的，但当我尝试运行它时，我得到以下结果

Exception in thread "main" java.lang.NoClassDefFoundError: org/eclipse/swt/widgets/Composite
        at java.lang.Class.getDeclaredMethods0(Native Method)

这是我的pom.xml

</project>

我是否需要用eclipse做一些其他的事情才能正确地加载swt库？我需要做什么才能让JVM识别swt，maven不应该在我的jar或类似的东西上打包swt。

Answer 1

尝试此存储库：

<repositories>
    <repository>
        <id>swt-repo</id>
        <url>https://swt-repo.googlecode.com/svn/repo/</url>
    </repository>
</repositories>

然后你可能会有更多的运气与依赖性：

<dependencies>
    <dependency>
        <groupId>org.eclipse.swt</groupId>
        <artifactId>org.eclipse.swt.gtk.linux.x86_64</artifactId>
        <version>4.3</version>
    </dependency>
</dependencies>
