我尝试通过带有注释@SuppressWarnings
的checkstyle在eclipse中忽略或禁用一些无用的警告
How to disable a particular checkstyle rule for a particular line of code?
但这对我不起作用。
这是checkstyle.xml
<module name="Checker">
<property name="severity" value="warning"/>
<module name="SuppressWarningsFilter"/>
<module name="TreeWalker">
<property name="tabWidth" value="4"/>
<module name="FileContentsHolder"/>
<module name="SuppressWarningsHolder"/>
<module name="CyclomaticComplexity"/>
...
这里是java代码:
@SuppressWarnings("checkstyle:CyclomaticComplexity")
public void doSomeThing() {
...
}
同时将警告值设置为“全部”@SuppressWarnings("all")
或@SuppressWarnings("CyclomaticComplexity")
,@SuppressWarnings("cyclomaticcomplexity")
没有任何结果。
checkstyle的文档很差。一些想法?

:一种。抑制警告过滤器
使用checkstyle 6.5.0我可以使用@SuppressWarnings。请考虑以下几点:
checkstyle模块的一些示例&#34; MagicNumber&#34;:
<强>使用:强>
@SuppressWarnings("checkstyle:magicnumber")
public example(){
int g = 5;
}
@SuppressWarnings("magicnumber")
public example(){
int g = 5;
}
不起作用:
@SuppressWarnings("MagicNumber")
public example(){
int g = 5;
}
。
@SuppressWarnings("magicNumber")
public example(){
int g = 5;
}
public example(){
@SuppressWarnings("magicnumber")
int g = 5;
}
进一步说明
我收到了警告不支持的抑制警告,我在Eclipse偏好设置中禁用了Java =&gt;编译器=&gt;错误/警告=&gt;注释=&gt;&#中未处理的令牌39; @ SuppressWarnings&#39;:忽略
相应的checkstyle模块的名称(在xml文件中定义)
&lt; module name =&#34; AnonInnerLength&#34;&gt;
&lt; property name =&#34; id&#34;值=&#34; CheckStyle的:anoninnerlength&#34; /&GT;
&LT;模块&GT;
我使用前缀&#34; checkstyle:&#34;在模块ID以及SuppressWarnings标记中,使其明确表示警告不是标准的Eclipse警告&#34;。 (可选前缀&#34; checkstyle:&#34;已经可以在标记中使用而不更改模块ID。但是,前缀不会显示在违规消息中。将其包含在模块ID中会使消息更多透明并激励我的同事在标签中包含前缀。)
<强> B中。抑制评论过滤器
<强>使用:强>
//CHECKSTYLE:OFF: checkstyle:magicnumber
public example(){
int g = 5;
}
//CHECKSTYLE:ON: checkstyle:magicnumber
//CHECKSTYLE:OFF: MagicNumber
public example(){
int g = 5;
}
//CHECKSTYLE:ON: MagicNumber
不起作用:
//CHECKSTYLE:OFF: magicnumber
public example(){
int g = 5;
}
//CHECKSTYLE:ON: magicnumber

答案 1 :(得分:6)
我的checkstyle版本为8.1
。
它适用于这样的gradle配置:
build.gradle
:
apply plugin: 'checkstyle'
checkstyle {
configFile = file('config/checkstyle.xml')
toolVersion = '8.1'
}
并忽略这样的幻数:
@SuppressWarnings("checkstyle:MagicNumber")
private String f(String a) {
String b = a.substring(0, 7);
String c = a.substring(a.length() - 3);
return b + "-" + c;
}
注意:前缀checkstyle:
是可选的。
希望这可以帮助别人。

只是强调Caio Faustino的评论,该评论至少在checkstyle 8.19上解决了该问题。
