blocks|key|340478|text|我遇到了同样的问题，上面的解决方案都没有解决它。最后解决这个问题的方法是选择模块并进入模块设置(在模块名称上按F4键)|type|unstyled|depth|inlineStyleRanges|entityRanges|data|340479|然后在Sources选项卡中，选择"java“文件夹并按下Sources按钮。这告诉IntelliJ有问题的文件夹是源代码文件夹。|340480|然后选择Test文件夹并按Tests。|340481|就这样。然后，它将正确识别这些文件，并根据需要显示错误。|340482|请看下面的截图。|340483|​|340484|📷|atomic|offset|length|340485|340486|entityMap|0|IMAGE|mutability|IMMUTABLE|imageUrl|https://ask.qcloudimg.com/http-save/yehe-900000/5be9965d09d1732bb2cbb728ad74571a.png|imageAlt^0|0|0|0|0|0|0|0|1|0|0|0^^$0|@$1|2|3|4|5|6|7|10|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|11|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|12|8|@]|9|@]|A|$]]|$1|F|3|G|5|6|7|13|8|@]|9|@]|A|$]]|$1|H|3|I|5|6|7|14|8|@]|9|@]|A|$]]|$1|J|3|K|5|6|7|15|8|@]|9|@]|A|$]]|$1|L|3|M|5|N|7|16|8|@]|9|@$O|17|P|18|1|19]]|A|$]]|$1|Q|3|K|5|6|7|1A|8|@]|9|@]|A|$]]|$1|R|3|-4|5|6|7|1B|8|@]|9|@]|A|$]]]|S|$T|$5|U|V|W|A|$X|Y|Z|-4]]]]

I had the same problem and none of the above solution solved it.
The thing that at the end solved it was by selecting the module and going to the module settings(press F4 on the module name)

Then in the Sources tab, select the "java" folder and press on the Sources button. 
That tells IntelliJ that the folder in question is a source code folder. 

Then select the Test folder and press Tests. 

That's it. Then it will recognize correctly the files and show errors as needed.

See below the screenshot.

blocks|key|340578|text|我的特定java文件名未在“文本文件”(IntelliJ+2019.3)中列出。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|340579|在关闭IntelliJ，然后在.Intellij2019.3中输入文件名之后，我在这里找到了一个匹配项：.Intellij2019.3\config\options\filetypes.xml。|340580|删除名称后，IntelliJ再次将该文件视为Java文件。|340581|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|H|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|I|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|J|8|@]|9|@]|A|$]]|$1|F|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|G|$]]

My specific java filename was not listed in 'Text files' (IntelliJ 2019.3).
After shutting down IntelliJ, then grepping for the filename in .Intellij2019.3,
I found a match here: .Intellij2019.3\config\options\filetypes.xml.
After removing the name, IntelliJ sees the file as Java file again.

blocks|key|340614|text|当我创建一个新的接口BenefitService.java它作为一个简单的文本文件时，我得到了这个错误。错误如下所示：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|340615|Unable+to+parse+template+“Interface”

I got this error when I created a new interface <code>BenefitService.java</code> it take as a simple text file. The error looks like this:
<pre><code>Unable to parse template “Interface”
 Error message: Selected class file name ‘BenefitService.java’ mapped to not java file type ‘Auto-detect file type by content`

So just go IntellJ File -&gt; Settings -&gt; Editor -&gt; File Types-&gt;Auto detect file type content and remove your file name eg in my case BenefitService.java it will work

blocks|key|122876|text|文件不着色还有另一个原因。我发现RubyMine在分析文件时会被卡住，然后它就不会给文件着色了。对我来说，当RubyMine对从yml文件转换/获取关键字感到困惑时，例如在单个视图文件的视图和控制器中都隐含yml文件时，.html.slim文件就会发生这种情况。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|122877|重命名文件似乎可以解决它，但这是因为它不再陷入解析yml文件的困境，但您认为这是文件关联问题。|122878|测试它的另一种方法是注释掉所有内容，在slim的情况下使用/。然后关闭文件并重新打开。然后对其进行着色，以便进行注释。删除注释就可以了，因为Rubymine在打开文件后不会尝试解析yml数据。但是关闭然后重新打开，当它变得混乱时，它又被卡住了。|122879|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|H|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|I|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|J|8|@]|9|@]|A|$]]|$1|F|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|G|$]]

There's another reason for a file not being coloured in. I've found RubyMine can get stuck analyzing a file, and then it doesn't colour it in. For me this happens on .html.slim files when RubyMine gets confused translating/fetching keys from yml files, for example when implying yml files in both views and controller on a single view file.
Renaming the file appears to fix it, but that's because it no longer gets stuck resolving the yml files, but you think it's the file association problem.
Another way to test it is to comment everything out, using / in the case of slim. Then close file and re-open. It is then coloured for being commented. Remove the comments and it works because Rubymine doesn't try to resolve yml data after the file is opened. But closing then re-open and it gets stuck again as it gets confused.

blocks|key|340546|text|我在创建一个新的java类时遇到了同样的问题，这个问题发生在Header.java上，可以用命令crt%2Balt%2Bs访问它，然后转到编辑器/文件和代码模板/Includes，这可能是以下格式：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|340547|/**+*由Alex+Leporoni在${DATE}创建。*/|340548|这解决了我的问题，现在我可以重新创建类了:)我希望这篇文章可以帮助其他有同样问题的人在IntelliJIdea上创建类……拥抱所有人。|340549|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|H|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|I|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|J|8|@]|9|@]|A|$]]|$1|F|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|G|$]]

I had the same problem to creat a new class java, the issue was on Header.java that can be access with the command crt+alt+s and go to Editor/FileAndCodeTemplates/Includes and this may be on this format: 

/**

This is solved my issue, now I can create classes again :) 
I hope that this article can help others that have the same problems to creat classes on IntelliJIdea... hugs to all.

There is a freemarker file (ftl) in my IntelliJ project that is incorrectly recognized as a text file. There are many of the same type that are correct.
I am aware of the &quot;Mark as text&quot; option. This may be the original reason this file was marked as text but I am not provided with a &quot;mark as ftl file&quot; option to turn it back, if indeed this is the problem. If I mark other ftl files as txt, I am able to turn them back into ftl files as expected.

IntelliJ not recognizing a particular file correctly, instead it's stuck as a text file

Java

我的IntelliJ项目中有一个freemarker文件(ftl)，它被错误地识别为文本文件。有许多相同类型的是正确的。我知道“标记为文本”选项。这可能是这个文件被标记为文本的原始原因，但如果这确实是问题所在，我没有提供“标记为ftl文件”选项来将其返回。如果我将其他ftl文件标记为txt，我可以将它们转换回预期的ftl文件。
