Question

我正在尝试从Maven exec插件启动Rails应用程序。我正在使用./script/rails server启动服务器，kill -9 cat tmp/pids/server.pid停止服务器。但是exec在服务器启动后一直在等待。是否有可能在后台运行这样的shell命令而不是等待？有没有更好的方法从Maven启动/停止rails应用程序？这是我的pom.xml：

            <plugin>
                <groupId>org.codehaus.mojo</groupId>
                <artifactId>exec-maven-plugin</artifactId>

                        <phase>pre-integration-test</phase>
                        <configuration>
                            <executable>script/rails</executable>
                            <workingDirectory>${rails.app.dir}</workingDirectory>
                            <arguments>
                                <argument>server</argument>
                            </arguments>
                        </configuration>
                        <goals>
                            <goal>exec</goal>
                        </goals>
                    </execution>
                    <execution>

                            <executable>kill -9 `cat tmp/pids/server.pid`</executable>
                            <workingDirectory>${rails.app.dir}</workingDirectory>
                        </configuration>
                        <goals>
                            <goal>exec</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>

传递-d参数以作为守护程序启动服务器：rails server -d。

以下是rails server命令的详细信息：

rails server -h
Usage: rails server [mongrel, thin, etc] [options]
    -p, --port=port                  Runs Rails on the specified port.
                                     Default: 3000
    -b, --binding=ip                 Binds Rails to the specified ip.
                                     Default: 0.0.0.0
    -c, --config=file                Use custom rackup configuration file
    -d, --daemon                     Make server run as a Daemon.
    -u, --debugger                   Enable ruby-debugging for the server.
    -e, --environment=name           Specifies the environment to run this server under (test/development/production).
                                     Default: development
    -P, --pid=pid                    Specifies the PID file.
                                     Default: tmp/pids/server.pid

    -h, --help                       Show this help message.
