我正在使用它lesscss-maven-plugin生成不同的css文件到目标目录(target\generated-sources),然后用于maven-war-plugin将此目录添加为webResouce.这些文件将生成完美的.

但是,m2e-plugin(版本1.0.0)在更改m2e-wtp\web-resources时不会复制相应web-resources文件夹()中的那些文件.只有当我运行eclipse"maven/update project"时,才会更新更改.但我希望更改在文件更改时自动生效.这是我的pom配置:

<plugin>

<artifactId>lifecycle-mapping</artifactId>
<version>1.0.0</version>

    <lifecycleMappingMetadata>

                    <goals>

                    </goals>
                </pluginExecutionFilter>
                <action>
                    <execute>
                        <runOnIncremental>true</runOnIncremental>
                        <runOnConfiguration>true</runOnConfiguration>
                    </execute>
                </action>
            </pluginExecution>  
        </pluginExecutions>
    </lifecycleMappingMetadata>
</configuration>
