How to force IntelliJ to download javadocs with Maven?
提问by Dims
I have the following descriptions for some Maven entries in Project Structure:
我对项目结构中的一些 Maven 条目有以下描述：
Javadoc file is really absent in filesystem. Simultaneously, it is present in central repository. Why it was not downloaded and how to download it by force?
文件系统中确实不存在 Javadoc 文件。同时，它存在于中央存储库中。为什么没有下载，如何强制下载？

Click on the "maven projects" (make sure tool buttons are on) on the right side of intelij and then click on "Download Documentation".
单击 intelij 右侧的“maven 项目”（确保工具按钮已打开），然后单击“下载文档”。
Also, for future downloading you can go to the File -> Settings -> Build,execution, deployment, -> build tools -> Maven -> importing -> mark "Documentation" checkbox and apply settings
此外，为了将来下载，您可以转到文件 -> 设置 -> 构建、执行、部署，-> 构建工具 -> Maven -> 导入 -> 标记“文档”复选框并应用设置

For me, it worked when I pressed on Download Source and Documentation.
对我来说，当我按下“下载源代码和文档”时它起作用了。

By the way, if you experience same case with me (working with corporate Maven repository), Maven may be ignoring an opportunity to further download javadoc if it once wasn't there. And to make it request it one more time, you have to remove <artifactId>-<version>-javadoc.jar.lastUpdatedfile from .m2/repository/<groupId>/<artifactId>/<version>, then try again.
顺便说一句，如果您遇到与我相同的情况（使用公司 Maven 存储库），Maven 可能会忽略进一步下载 javadoc 的机会，如果它曾经不存在的话。为了让它再次请求它，您必须从 中删除<artifactId>-<version>-javadoc.jar.lastUpdated文件.m2/repository/<groupId>/<artifactId>/<version>，然后再试一次。
