我正在尝试 运行 .jar file 中的一个程序。要在 te 项目目标文件夹中创建 .jar file，我使用了命令 mvn clean package spring-boot:repackage.
在我使用 java -jar middleware-0.0.1-SNAPSHOT.jar 启动程序后出现一条错误消息。

在我的 IDE (Eclipse) 中一切正常，但是 .jar file 抛出了上面的错误。
我知道很多人都有这个问题，但他们中的大多数人都试图加载一个文件（例如。xml），而我正在尝试实现一个接口。我不知道这有多少不同。
如果你能帮助我，我将不胜感激。提前致谢-
检查 jar 中是否包含系统范围的依赖项！您可以使用任何压缩工具解压缩 jar。
如果要包含它，请检查 spring-boot:repackage 目标的 includeSystemScope 选项：
https://docs.spring.io/spring-boot/docs/1.4.1.RELEASE/maven-plugin/repackage-mojo.html#includeSystemScope
只是一个例子，所以你可以看到如何添加选项。它已添加到项目的 pom.xml 文件中。
[...]
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<configuration>
<mainClass>full.qualified.MainClass</mainClass>
<layout>ZIP</layout>
<classifier>exec</classifier>
<includeSystemScope>true</includeSystemScope>
</configuration>
<executions>
<execution>
<goals>
<goal>repackage</goal>
</goals>
</execution>
</executions>
</plugin>
[...]
如果不想包含它，则必须在执行 jar 时将 jar 添加到类路径中：
（Unix 风格）
java -cp "middleware-0.0.1-SNAPSHOT.jar:C:\Users\mfi\Downloads\LaunchableJar\remote.jar" -Dloader.main=<YOUR_MAINCLASS_HERE> org.springframework.boot.loader.PropertiesLauncher "$@"
我正在尝试 运行 .jar file 中的一个程序。要在 te 项目目标文件夹中创建 .jar file，我使用了命令 mvn clean package spring-boot:repackage.
在我使用 java -jar middleware-0.0.1-SNAPSHOT.jar 启动程序后出现一条错误消息。

在我的 IDE (Eclipse) 中一切正常，但是 .jar file 抛出了上面的错误。
我知道很多人都有这个问题，但他们中的大多数人都试图加载一个文件（例如。xml），而我正在尝试实现一个接口。我不知道这有多少不同。
如果你能帮助我，我将不胜感激。提前致谢-
检查 jar 中是否包含系统范围的依赖项！您可以使用任何压缩工具解压缩 jar。
如果要包含它，请检查 spring-boot:repackage 目标的 includeSystemScope 选项： https://docs.spring.io/spring-boot/docs/1.4.1.RELEASE/maven-plugin/repackage-mojo.html#includeSystemScope
只是一个例子，所以你可以看到如何添加选项。它已添加到项目的 pom.xml 文件中。
[...]
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<configuration>
<mainClass>full.qualified.MainClass</mainClass>
<layout>ZIP</layout>
<classifier>exec</classifier>
<includeSystemScope>true</includeSystemScope>
</configuration>
<executions>
<execution>
<goals>
<goal>repackage</goal>
</goals>
</execution>
</executions>
</plugin>
[...]
如果不想包含它，则必须在执行 jar 时将 jar 添加到类路径中：
（Unix 风格）
java -cp "middleware-0.0.1-SNAPSHOT.jar:C:\Users\mfi\Downloads\LaunchableJar\remote.jar" -Dloader.main=<YOUR_MAINCLASS_HERE> org.springframework.boot.loader.PropertiesLauncher "$@"
