What build tool do you use? You obviously forgot to declare your dependencies, that's why IDEA doesn't know where to look for the classes you are trying to import.

blocks|key|5138461|text|如果在试图导入Maven项目后出现此错误，则可能需要在import向导中检查"Import自动“。否则，IntelliJ构建可能无法定位Maven依赖项，即使它们是在pom.xml文件中声明的。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|5138462|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

If you get this error after attempting to import a Maven project, it may be that you need to check "Import Maven projects automatically" in the Import Project wizard. Without that the IntelliJ build may not be able to locate Maven dependencies, even if they are declared in pom.xml files.

blocks|key|5138499|text|您只需要在验证API+pom.xml中添加。|type|unstyled|depth|inlineStyleRanges|offset|length|style|BOLD|entityRanges|data|5138500|​|5138501|<dependency>

You just need to add the dependency Validation API in the pom.xml:
<div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
<div class="snippet-code">
<pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;dependency&gt;
 &lt;groupId&gt;javax.validation&lt;/groupId&gt;
 &lt;artifactId&gt;validation-api&lt;/artifactId&gt;
 &lt;version&gt;2.0.0.Final&lt;/version&gt;
&lt;/dependency&gt;</code></pre>
</div>

blocks|key|4728733|text|尝尝这个,|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4728734|一步步地：|4728735|打开"build.gradle“文件。它在你的根文件夹项目中；|ordered-list-item|4728736|在“依赖项{}”中包含以下一行:实现组：'javax.validation'，名称：‘validation’，version：'2.0.1.Final‘|4728737|保存和关闭build.gradle文件；|4728738|接下来，您将在屏幕顶部看到一个简短的通知："Load更改“。单击它。|4728739|如果没有看到任何通知，请单击Gradle侧栏，然后单击"Reload项目“。|4728740|就这样!您的注释@Valid，@NotBlank+ou+@NotNull将有效。|4728741|entityMap^0|0|0|0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|S|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|T|8|@]|9|@]|A|$]]|$1|D|3|E|5|F|7|U|8|@]|9|@]|A|$]]|$1|G|3|H|5|F|7|V|8|@]|9|@]|A|$]]|$1|I|3|J|5|F|7|W|8|@]|9|@]|A|$]]|$1|K|3|L|5|F|7|X|8|@]|9|@]|A|$]]|$1|M|3|N|5|6|7|Y|8|@]|9|@]|A|$]]|$1|O|3|P|5|F|7|Z|8|@]|9|@]|A|$]]|$1|Q|3|-4|5|6|7|10|8|@]|9|@]|A|$]]]|R|$]]

Try this,
Step-by-step:
<ol>
<li>Open &quot;build.gradle&quot; file. It's in your root folder project;
</li>
<li>Include the line below inside &quot;dependencies{ }&quot;:
implementation group: 'javax.validation', name: 'validation-api', version: '2.0.1.Final'
</li>
<li>Save and close build.gradle file;
</li>
<li>Next, you will see a short notification on the top of your screen to &quot;Load Gradle Changes&quot;. Click on it.
</li>
</ol>
If you don't see any notification, click on Gradle side bar, and then click on &quot;Reload All Gradle Projects&quot;.
<ol start="5">
<li>That's all! Your annotation @Valid, @NotBlank ou @NotNull, will work.</li>
</ol>

I can't import that simple library, i have all jar files, also i tried Ivalidate Caches / Restart. Maybe i have to add validation to build path, but i don't know to which file.

我不能导入这个简单的库，我有所有的jar文件，我还尝试了Ivalidate / Restart。也许我必须添加验证来构建路径，但我不知道是哪个文件。​
