我正在使用两个插件来生成一个带有来自eclipse的m2e插件的可运行jar文件。这是配置:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<version>2.3.2</version>
<configuration>
<archive>
<manifest>
<mainClass>com.unlockservice.App</mainClass>
<addClasspath>true</addClasspath>
<classpathPrefix>lib/</classpathPrefix>
</manifest>
</archive>
</configuration>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<version>2.1</version>
<executions>
<execution>
<id>copy-dependencies</id>
<phase>package</phase>
<goals>
<goal>copy-dependencies</goal>
</goals>
<configuration>
<outputDirectory>${project.build.directory}/lib</outputDirectory>
<overWriteReleases>false</overWriteReleases>
<overWriteSnapshots>false</overWriteSnapshots>
<overWriteIfNewer>true</overWriteIfNewer>
</configuration>
</execution>
</executions>
</plugin>
除了标准依赖项之外,我还有几个本地的依赖项,以下列方式添加:
<dependency>
<groupId>com.ejl</groupId>
<artifactId>CRMObjects</artifactId>
<version>1.0</version>
<scope>system</scope>
<systemPath>${basedir}/lib/CRMObjects.jar</systemPath>
</dependency>
<dependency>
<groupId>com.ejl</groupId>
<artifactId>CRMPDFGenerators</artifactId>
<version>1.0</version>
<scope>system</scope>
<systemPath>${basedir}/lib/CRMPDFGenerators.jar</systemPath>
</dependency>
在maven的构建之后,一切看起来都很好。所有库都复制到lib文件夹。但是当我将jar文件和lib文件夹复制到服务器并使用java -jar path-to-file.jar
运行文件时,它失败了,因为无法从外部库(CRMObjects.jar)找到类。
有什么建议吗?提前谢谢

Java并不知道在哪里可以找到您的库jar。你需要一个&#34; Class-Path:lib / jar1.jar lib / jar2.jar&#34;在应用程序jar中的清单文件中键入条目,或者需要在命令行上设置类路径。请参阅此答案:https://stackoverflow.com/a/219801/1271971

最后使用了两个插件:
<plugin>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.1</version>
<configuration>
<source>1.6</source>
<target>1.6</target>
</configuration>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-shade-plugin</artifactId>
<version>2.3</version>
<executions>
<execution>
<phase>package</phase>
<goals>
<goal>shade</goal>
</goals>
</execution>
</executions>
<configuration>
<finalName>${project.artifactId}-${project.version}</finalName>
<transformers>
<transformer implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
<resource>META-INF/spring.handlers</resource>
</transformer>
<transformer implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
<resource>META-INF/spring.schemas</resource>
</transformer>
<transformer implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
<mainClass>com.main.App</mainClass>
</transformer>
</transformers>
<filters>
<filter>
<artifact>*:*</artifact>
<excludes>
<exclude>META-INF/*.SF</exclude>
<exclude>META-INF/*.DSA</exclude>
<exclude>META-INF/*.RSA</exclude>
</excludes>
</filter>
</filters>
</configuration>
</plugin>
最后,我有完整的可执行jar文件,其中包含所有依赖项和库。
