Question

我跟随getting started guide的bootique.io，我似乎遇到了一些可能与我的maven配置相关的内容，或者可能与bootique.io中最近发生的变化有关＃39; t在入门指南中介绍。

我创建了一个简单的github项目，跟随指南here（git clone和mvn包，java -jar target / bootique-tryout-1-jar-with-dependencies.jar）运行）。

入门指南指出在编译和运行jar之后，您应该看到一个如下所示的选项列表：

NAME
      com.foo.Application

OPTIONS
      -c yaml_location, --config=yaml_location
           Specifies YAML config location, which can be a file path or a URL.

      -h, --help
           Prints this message.

      -H, --help-config
           Prints information about application modules and their configuration
           options.

      -s, --server
           Starts Jetty server.

但是，当我运行上述后续版本时，我会看到：

NAME
      bootique-tryout-1-jar-with-dependencies.jar

OPTIONS
      -c yaml_location, --config=yaml_location
           Specifies YAML config location, which can be a file path or a URL.

      -h, --help
           Prints this message.

      -H, --help-config
           Prints information about application modules and their configuration
           options.

注意缺少-s, --server选项。什么（显而易见的？）我错过了什么？

啊，在论坛上乱后一点，我发现这是由于一些bootique特定设置处理由maven-assembly-plugin和maven-shade-plugin生成的组合jar。

我删除了基于jar-with-dependencies的maven-assembly-plugin并将其替换为maven-shade-plugin，配置如下：

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-shade-plugin</artifactId>
            <version>3.1.1</version>
            <configuration>
                <createDependencyReducedPom>true</createDependencyReducedPom>
                <filters>
                    <filter>
                        <artifact>*:*</artifact>
                        <excludes>
                            <exclude>META-INF/*.SF</exclude>
                            <exclude>META-INF/*.DSA</exclude>
                            <exclude>META-INF/*.RSA</exclude>
                        </excludes>
                    </filter>
                </filters>
            </configuration>
            <executions>
                <execution>
                    <phase>package</phase>
                    <goals>
                        <goal>shade</goal>
                    </goals>
                    <configuration>
                        <transformers>
                            <transformer implementation="org.apache.maven.plugins.shade.resource.ServicesResourceTransformer" />
                            <transformer implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
                                <mainClass>${main.class}</mainClass>
                            </transformer>
                        </transformers>
                    </configuration>
                </execution>
            </executions>
        </plugin>

当我现在mvn clean package并尝试运行该应用程序时，我按预期看到-s, --server选项：

NAME
      bootique-tryout-1.jar

OPTIONS
      -c yaml_location, --config=yaml_location
           Specifies YAML config location, which can be a file path or a URL.

      -h, --help
           Prints this message.

      -H, --help-config
           Prints information about application modules and their configuration
           options.

      -s, --server
           Starts Jetty server.

我已使用上述修复程序更新了my example project。

Bootique，运行主要示例，服务器选项未显示
