Question

所以我创建了一个独立的应用程序，它会生成一个jar。当我从Eclipse运行它时，它可以运行，“Run As” - ＆gt; java应用程序。

当我尝试从控制台运行它时，我开始从swt中获取问题，所以我添加到我的清单swt.jar中，我开始遇到我的下一个依赖于我的pom的问题。

以下是我的swom.jar

的pom.xml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jar的同一个文件夹中。但我不想手动将所有库添加到清单中。感觉应该有一种更简单，更有效的方式来做到这一点。

这是我添加swt后得到的错误

$ java -jar mapper.jar

之前完全相同但有一些swt图形库。这是我的pom.xml

Answer 1

尝试使用Maven Dependency Plugin复制jar，使用“addClasspath”节点复制Maven JAR插件，将依赖项添加到清单中：

<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并将它们添加到前缀为lib /

的清单中
