提问by
What to import to use SuppressFBWarnings? I installed the findbugs plugin via help / install new software When I type import edu., I can't do ctrl space to get the options.
要导入什么才能使用 SuppressFBWarnings？我通过帮助安装了 findbugs 插件/安装新软件当我输入 import edu. 时，我无法按 ctrl 空间来获取选项。
Example
例子
try {
String t = null;
@edu.umd.cs.findbugs.annotations.SuppressFBWarnings(
value="NP_ALWAYS_NULL",
justification="I know what I'm doing")
int sl = t.length();
System.out.printf( "Length is %d", sl );
} catch (Throwable e) {
...
}
Has error "edu cannot be resolved to a type"
出现错误“edu 无法解析为类型”

In order to use the FindBugs annotations, you need to include annotations.jarand jsr305.jarfrom the FindBugs distribution on your classpath. If you are sure that you want the @SuppressFBWarningsannotation only (and not the others), then annotations.jaralone would be sufficient.
为了使用 FindBugs 注释，您需要在类路径中包含来自 FindBugs 发行版的annotations.jar和jsr305.jar。如果您确定@SuppressFBWarnings只需要注释（而不是其他注释），那么仅annotations.jar就足够了。
You can find the two JARs in the libfolder of the FindBugs distribution.
您可以在FindBugs 发行版的lib文件夹中找到这两个 JAR 。
If you are using Maven:
如果您使用的是 Maven：
<dependency>
<groupId>com.google.code.findbugs</groupId>
<artifactId>annotations</artifactId>
<version>3.0.1</version>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>com.google.code.findbugs</groupId>
<artifactId>jsr305</artifactId>
<version>3.0.1</version>
<scope>provided</scope>
</dependency>
If you are using Gradle:
如果您使用的是 Gradle：
dependencies {
compileOnly 'com.google.code.findbugs:annotations:3.0.1'
compileOnly 'com.google.code.findbugs:jsr305:3.0.1'
}
compileOnlyis the Gradle flavor of what Maven calls providedscope.
compileOnly是 Maven 称为provided范围的 Gradle 风格。
Update for SpotBugs (2018):
SpotBugs 更新（2018 年）：
FindBugs has been superseded by SpotBugs. So if you are already using SpotBugs, the migration guidesuggests that you use the following dependencies instead:
FindBugs 已被SpotBugs取代。因此，如果您已经在使用 SpotBugs，迁移指南建议您改用以下依赖项：
Please depend on both of spotbugs-annotationsand net.jcip:jcip-annotations:1.0instead.
请同时使用spotbugs-annotations和net.jcip:jcip-annotations:1.0。
Maven:
马文：
<dependency>
<groupId>net.jcip</groupId>
<artifactId>jcip-annotations</artifactId>
<version>1.0</version>
<optional>true</optional>
</dependency>
<dependency>
<groupId>com.github.spotbugs</groupId>
<artifactId>spotbugs-annotations</artifactId>
<version>3.1.3</version>
<optional>true</optional>
</dependency>
Gradle:
摇篮：
dependencies {
compileOnly 'net.jcip:jcip-annotations:1.0'
compileOnly 'com.github.spotbugs:spotbugs-annotations:3.1.3'
}
If you also used jsr305, that dependency remains the same as above.
如果您还使用了jsr305，则该依赖项与上述相同。
