java - Eclipse 说 : Web Fragment Module 3. 0 需要 Java 1.6 或更高版本，但我的项目方面未设置

Question

我正在开发一个 java maven 项目，并且 eclipse 在标题上提示此消息。

但是如果我查看我的项目方面，它们不会被检查，正如您在此图片中所看到的:

还在我的 pom.xml 上，我没有看到任何有关此配置的信息:

那么 Eclipse 如何知道这是 Web Fragment 3.0？

Answer 1

我现在看到它在/META-INF 下包含一个 web-fragment.xml 文件，因此这可能会泄露它。 :)

我将其添加到我的 pom.xml 中，它似乎已经消除了错误消息:

        <plugin> 
            <groupId>org.apache.maven.plugins</groupId> 
            <artifactId>maven-compiler-plugin</artifactId> 
            <configuration> 
                <source>1.7</source> 
                <target>1.7</target> 
            </configuration> 
        </plugin>
