有什么方法可以触发Maven Appengine Devserver自动刷新静态文件吗? [英] Is there any way to trigger the Maven Appengine Devserver to auto-refresh static files?

问题描述

最新版本的maven插件启用了每5秒更新一次代码的功能，这是一个很大的改进.但是，除非我配置错误，否则似乎不会拾取静态文件更改，例如正在进行的Javascript连接到appengine代码.
有什么办法可以改变这种行为，还是我只需要等待一个新版本?

The most recent version of the maven plugin has enabled updating of code every 5s, which is a great improvement. But unless I am configuring this wrong, it doesn't seem to pick up static file changes such as work in progress Javascript connecting to the appengine code.
Is there any way to alter this behavior or do I just need to wait for a new release?

推荐答案

到目前为止，我发现的最佳方法是在pom.xml中配置以下条目.这将自动生成您的静态文件并反映在页面上.

So far, best way i found was configuring below entries in pom.xml. This will build automatically your static files and reflects on the page.

<plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-antrun-plugin</artifactId>
            <version>1.7</version>
            <executions>
                <execution>
                    <phase>process-classes</phase>
                    <goals>
                        <goal>run</goal>
                    </goals>
                    <configuration>
                        <target>
                            <property name="target.webapp.dir"
                                value="${project.build.directory}/${project.build.finalName}" />
                            <property name="src.webapp.dir" value="${basedir}/src/main/webapp" />

                            <sync verbose="true" todir="${target.webapp.dir}"
                                includeEmptyDirs="true">
                                <fileset dir="${src.webapp.dir}" />
                                <preserveintarget>
                                    <include name="WEB-INF/lib/**" />
                                    <include name="WEB-INF/classes/**" />
                                    <include name="WEB-INF/appengine-generated/**" />
                                </preserveintarget>
                            </sync>

                            <!-- <sync verbose="true" todir="${target.webapp.dir}/WEB-INF/classes"> 
                                <fileset dir="${basedir}/target/classes" /> </sync> -->

                        </target>
                    </configuration>
                </execution>
            </executions>
        </plugin>

以及

<pluginManagement>
        <plugins>
            <!-- This plugin's configuration is used to store Eclipse m2e settings 
                only. It has no influence on the Maven build itself. -->
            <plugin>
                <groupId>org.eclipse.m2e</groupId>
                <artifactId>lifecycle-mapping</artifactId>
                <version>1.0.0</version>
                <configuration>
                    <lifecycleMappingMetadata>
                        <pluginExecutions>
                            <pluginExecution>
                                <pluginExecutionFilter>
                                    <groupId>org.apache.maven.plugins</groupId>
                                    <artifactId>maven-antrun-plugin</artifactId>
                                    <versionRange>[1.6,)</versionRange>
                                    <goals>
                                        <goal>run</goal>
                                    </goals>
                                </pluginExecutionFilter>
                                <action>
                                    <execute>
                                        <runOnIncremental>true</runOnIncremental>
                                    </execute>
                                </action>
                            </pluginExecution>
                        </pluginExecutions>
                    </lifecycleMappingMetadata>
                </configuration>
            </plugin>
        </plugins>
    </pluginManagement>

这很好.更改并保存任何静态文件后，该文件就会立即反映在页面上.

This is working fine. As soon as any static files changed and saved, it got reflected on the page.
