</ul>

This is because of newer chrome version.Use Super Dev Mode 

Other Solution is you can enable NPAPI which was disable in chrome 42 version follow the below steps

1.Open New Tab and Enter <code>chrome://flags/#enable-npapi</code>

2.Enable this <code>Enable NPAPI Mac, Windows</code>

3.Then bottom of the page click "Relunch" button.

I had the same issue this morning.

Switching to super dev mode:

select your project in the Project Explorer -> Debug as -> Web Application(Super Dev Mode)

Console will say: 
The code server is ready.
Next, visit: <a href="http://127.0.0.1:9876/">http://127.0.0.1:9876/</a>

Do so and follow instructions there.

blocks|key|360373|text|简单回顾一下:一年多前，火狐使用了DevMode在27.0版中所需的API；Chrome大约在同一时间宣布，他们反对NPAPI，这是DevMode需要的。一年前，他们首先使Chrome中包含NPAPI插件的扩展无法更新，然后在Linux上删除了NPAPI支持，现在他们刚刚在Chrome+42中禁用了NPAPI，并将在45号中完全删除支持，将于9月发布。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|360374|“经典”DevMode已经被废弃了将近一年半了；现在是时候转移到SuperDevMode了！|360375|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

Quick recap: Firefox nuked APIs that DevMode needed in 27.0, more than a year ago; Chrome announced approximately at the same time that they were deprecating NPAPI, that DevMode needs. They first made it impossible to update extensions containing NPAPI plugins in the Chrome Web Store a year ago, then they removed NPAPI support on Linux, and now they've just disabled NPAPI in Chrome 42, and will remove support entirely in 45, to be released in September.

"Classic" DevMode is deprecated for nearly 1½ year now; it really is time to move to SuperDevMode!

It's very likely that you are following word for word the instructions from Google at this link. 

<a href="https://developers.google.com/eclipse/docs/getting_started" rel="nofollow">https://developers.google.com/eclipse/docs/getting_started</a>

The instructions are out of date, and not valid for current versions of chrome.

Instead of selecting the option 

Debug As > Web Application 

use the option

Debug As > Web Application (GWT Super Dev Mode)

Google has "given up" on keeping their documentation up to date. I can only imagine how difficult it must be to ignore so many complaints.

NPAPI can be re-enabled in Chrome but it is going away.

Super dev mode supposed to be the way forward but I prefer the classic dev mode.

I'm using Windows. I installed a version of Chromium to stop this being a problem for me. The version I found to be the last of the 41 series was build 310958 which can be obtained here:

<a href="https://commondatastorage.googleapis.com/chromium-browser-snapshots/index.html?prefix=Win/310958/" rel="nofollow">https://commondatastorage.googleapis.com/chromium-browser-snapshots/index.html?prefix=Win/310958/</a>

You need to download the mini_installer.exe file. This version of Chromium will never update itself.

I recommend also that you make a copy of the GWT Developer Plugin that you can install without using Google's store because I believe it will be removed soon. I don't know how to do that, but one member of my team claims to have done it.

blocks|key|1405913|text|这是一个问题，因为Google现在已经完全放弃NPAPI，这是Google插件所需要的，在这里可以看到：http://blog.chromium.org/2013/09/saying-goodbye-to-our-old-friend-npapi.html。|type|unstyled|depth|inlineStyleRanges|offset|length|style|BOLD|entityRanges|data|1405914|谷歌现在提供了“超级开发模式”，它不需要NPAPI。|1405915|为了利用这个功能，您可以查看这个博客：https://www.sencha.com/blog/getting-started-with-gwt-super-dev-mode/|1405916|entityMap|0|LINK|mutability|MUTABLE|url|http://blog.chromium.org/2013/09/saying-goodbye-to-our-old-friend-npapi.html|1|https://www.sencha.com/blog/getting-started-with-gwt-super-dev-mode/^0|9|U|1G|24|0|0|0|J|1W|1|0^^$0|@$1|2|3|4|5|6|7|T|8|@$9|U|A|V|B|C]]|D|@$9|W|A|X|1|Y]]|E|$]]|$1|F|3|G|5|6|7|Z|8|@]|D|@]|E|$]]|$1|H|3|I|5|6|7|10|8|@]|D|@$9|11|A|12|1|13]]|E|$]]|$1|J|3|-4|5|6|7|14|8|@]|D|@]|E|$]]]|K|$L|$5|M|N|O|E|$P|Q]]|R|$5|M|N|O|E|$P|S]]]]

This issue is there, as Google has now completely discarded NPAPI which is required by GWT developer plugin which can been seen here:<a href="http://blog.chromium.org/2013/09/saying-goodbye-to-our-old-friend-npapi.html" rel="nofollow">http://blog.chromium.org/2013/09/saying-goodbye-to-our-old-friend-npapi.html</a>

Google now provides "Super Dev Mode" which does not require NPAPI.
