每次启动环境时，Eclipse 都会覆盖我的 web.xml

Question

我在 Windows 7 平台上运行 Eclipse Juno 和 Tomcat 7。

当我使用 Maven 构建我的项目时，web.xml 是正确派生的。我进入 eclipse 并刷新并检查我的 target\web.xml，到目前为止一切顺利。我运行 Tomcat 服务器，一切正常。

只要我重新启动 Eclipse，web.xml 就会回到占位符版本，我必须再次从 Maven 构建并在运行 Tomcat 之前刷新源代码。

我在 Ubuntu 上进行了完全相同的设置，但没有发生这种情况。

在 Project Facets 下，我使用的是 Dynamic Web Module 3.0。

如果您使用的是 m2e-wtp，首先请检查您使用的是最新版本，即 0.17。之后，资源过滤使用 Maven War plugin为了在标准构建阶段过滤它们:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-war-plugin</artifactId>
    <configuration>
        <webResources>
            <resource>
                <filtering>true</filtering>
                <directory>src/main/webapp</directory>
                <includes>
                    <include>**/*.xhtml</include>
                    <include>**/*.xml</include>
                </includes>
            </resource>
            <resource>
                <filtering>true</filtering>
                <directory>src/main/resources</directory>
                <includes>
                    <include>**/*.xml</include>
                    <include>**/*.properties</include>
                </includes>
                <targetPath>WEB-INF/classes</targetPath>
            </resource>
        </webResources>
    </configuration>
</plugin>
