我正在尝试使用Maven编译器插件来显示所有警告，如果有任何警告，则通过配置“Werror”参数使构建失败。我的maven编译器插件的Pom.xml文件设置是 -
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.5.1</version>
<configuration>
<forceJavacCompilerUse>true</forceJavacCompilerUse>
<source>1.7</source>
<target>1.7</target>
<compilerArgs>
<arg>-Xlint:all</arg>
<arg>-Xlint:-deprecation</arg>
<arg>-Xlint:-unchecked</arg>
<arg>-Xlint:-rawtypes</arg>
<arg>-g</arg>
<arg>Werror</arg>
</compilerArgs>
<verbose>true</verbose>
<showWarnings>true</showWarnings>
</configuration>
</plugin>
在我的项目中，我有3个警告 - 弃用，未选中，rawtypes。 如果我删除这些参数，那么构建失败，这是完全正常的。 -
<arg>-Xlint:-deprecation</arg>
<arg>-Xlint:-unchecked</arg>
<arg>-Xlint:-rawtypes</arg>
但是当我添加这些参数时，编译器应该忽略这些警告并且构建应该成功。 但是Build仍然失败并且没有显示任何特定错误。 如果删除此参数，构建成功。
<arg>Werror</arg>
所以我无法运行成功的构建如果我们跳过项目中存在的一些警告。有没有办法实现同样的目标？

在做了很多改变之后，我终于弄明白了如何用＆＃34; Werror＆＃34;如果所有Lint警告都已修复，则标记。
我删除了 - ＆＃34; true＆＃34; 无法弄清楚当我们使用Javac编译器时构建失败的原因。
添加了UTF-8编码并抑制了Processing Lint警告。
配置的工作副本是 -
public class MyObject {
public string MyProperty { get; set; }
}
