Java 从命令行运行Verticle时未找到包

我正在使用

Maven

和

Vert.x

创建一个应用程序。 当我在IDE（IntelliJ）中运行它时，一切都正常工作，但我无法使用命令行使其工作

我有一个

Launcher

类，它部署了一些verticle，但我所有的verticle都存在同样的问题

到目前为止，我已经尝试过：

vertx run Launcher.java
vertx run com.packagename.Launcher.java
// user-content-service-0.1.jar create via: mvn clean package
run com.packagename.Launcher.java -cp target\user-content-service-0.1.jar

作为错误，我得到以下信息：

.../path/Launcher.java:8: error: cannot find symbol
private static final Logger logger = logManager.getLogger(Launcher.class);

symbol: variable LogManager
location: class com.packagename.Launcher
java.lang.RuntimeException: Compilation failed
...

问题似乎来自编译器无法找到依赖项的事实

下面是我的

pom.xml

的样子：

你知道我在这里做错了什么吗

谢谢

您遇到了类路径问题；因为您在打包阶段使用maven jar打包jar文件，所以您只能在构建目录中得到它；如果您想在命令行上运行

java-jar

，您应该创建一个（又称uber-jar，一个专门打包的jar文件，用于包含您的类和pom文件中声明的所有依赖项）

您可以在软件包阶段添加此功能，即：

<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>
      <configuration>
        <transformers>
          <transformer implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
            <manifestEntries>
                <Main-Class>io.vertx.core.Launcher</Main-Class>
                <Main-Verticle>com.packagename.Launcher</Main-Verticle>
            </manifestEntries>
          </transformer>
          <transformer implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
              <resource>META-INF/services/io.vertx.core.spi.VerticleFactory</resource>
          </transformer>
        </transformers>
        <artifactSet/>
        <outputFile>${project.build.directory}/${project.artifactId}-${project.version}-fat.jar</outputFile>
      </configuration>
    </execution>
  </executions>
</plugin>

查看以了解更多信息。

第一个建议是停止使用

最新版本

，因为它已被长期弃用……并且您无法从命令行运行它，因为您尚未将所有依赖项打包到fat jar（maven assembly plugin）中或者类似的东西…请使用maven shade插件的最新版本，请参阅进一步删除

输出文件的配置，并保留约定。。。
