Question

我有一个maven项目，当我转向生产时，我希望构建在任何编译器警告上失败。

我查看了网页并使用this SO post

的指导配置了我的pom.xml

<plugin>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>2.4</version>
    <configuration>
        <source>1.7</source>
        <target>1.7</target>
        <compilerArgument>-Werror</compilerArgument>
        <compilerArgument>-Xlint</compilerArgument>
        <fork>true</fork>
    </configuration>
</plugin>

在我的项目中，我删除了一些参数化以创建未经检查的强制转换：

return ((Map<String, Object>)getProperty("settings", Map.class).get("aSetting");

eclipse和maven都将其正确识别为编译器警告。但是，尽管maven的编译日志中出现了警告，但该项目仍然可以编译并返回成功：

我在编译器配置中尝试了-Werror，-Xlint，fork，showWarning和showDepreciation的不同组合，但没有任何东西像我期望的那样产生编译错误。

Answer 1

使用

<compilerArguments>
    <Xlint/>
    <Xlint>cast</Xlint>
</compilerArguments>

Maven没有失败编译器警告
