所以我创建了一个独立的应用程序，它生成一个 jar。当我从 Eclipse 运行它时，它可以工作，“运行为”-> java 应用程序。
当我尝试从控制台运行它时，我开始从 swt 中遇到问题，因此我将其添加到我的 list swt.jar 中，然后我开始对 pom 的下一个依赖项出现问题。
这是我的 pom.xml 和 swt.jar 的示例
Manifest-Version: 1.0
Main-Class: mapper.osm.main.Main
Class-Path: swt.jar
我下载了 swt 并将其复制到我的 jar 的同一文件夹中。但我不想将所有库手动添加到我的 list 中。感觉应该有一种更简单、更行之有效的方法来做到这一点。
这是我添加swt后遇到的错误
$ java -jar mapper.jar

之前它是完全相同的，但带有一些 swt 图形库。 这是我的 pom.xml

最佳答案
尝试使用 Maven 依赖项插件复制 jar，并使用带有“addClasspath”节点的 Maven JAR 插件将依赖项添加到 list 中:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<executions>
<execution>
<id>copy-dependencies</id>
<phase>package</phase>
<goals>
<goal>copy-dependencies</goal>
</goals>
<configuration>
<outputDirectory>${project.build.directory}/lib</outputDirectory>
</configuration>
</execution>
</executions>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<configuration>
<archive>
<manifest>
<addClasspath>true</addClasspath>
<classpathPrefix>lib</classpathPrefix>
<mainClass>my.test.App</mainClass>
</manifest>
</archive>
</configuration>
</plugin>
这会将 jar 复制到 target/lib 并将它们添加到带有前缀 lib/的 list 中
