<p>hi, everyone</p>
<p>I am newbie for ovirt-engine development and maven, I meet some
questions about setup ovirt-engine development, which had blocked
me for almost ten days；I hope to get your help or some tips<br>
</p>
<p> the following description is the process of setup ovirt-engine
development:</p>
<p><br>
</p>
<p> After installing centos 7（CentOS-7-x86_64-DVD-1511.<wbr>iso）with
Minimal installation, then refer to <br>
</p>
<p>
<a class="m_-6262396123085546024moz-txt-link-freetext" href="http://www.ovirt.org/develop/developer-guide/engine/engine-development-environment/" target="_blank">http://www.ovirt.org/develop/<wbr>developer-guide/engine/engine-<wbr>development-environment/</a>
（I use ovirt-engine 4.1 version）<br>
</p>
<p>I can compile and run ovirt-engine on cenots 7, ovirt-engine web
page can be accessed normally, Moreover, after installing gnome
desktop on centos7 and setting up java IDE development （I use
Intellij idea-IC-171.4073.35 community edition）, I met some
questions about using Intellij idea IDE to debug ovirt-engine, the
following is my problem description:</p>
<p>I refer the following two links to build the developement
environment <br>
</p>
<p>
<a class="m_-6262396123085546024moz-txt-link-freetext" href="https://www.ovirt.org/develop/developer-guide/engine/building/ide/" target="_blank">https://www.ovirt.org/develop/<wbr>developer-guide/engine/<wbr>building/ide/</a></p>

<p> firstly, at ovirt-engine source directory, after mading the
following operation, I can attach to port 8000 under intellij
idea IDE environments, but debug can not be started <br>
</p>
<p> <code>#make gwt-debug DEBUG_MODULE="webadmin"
DEV_EXTRA_BUILD_FLAGS_GWT_<wbr>DEFAULTS="-Dgwt.userAgent=</code><code><code>geck<wbr>o1_8</code>"
（the picture b is output from the command）<br>
</code></p>
<p><code><img src="cid:part1.0FFE8AE6.EA85FFE8@linx-info.com" alt=""></code></p>
<p><code> the second picture below is a snapshot for Intellij idea
、GWT module and Web browser (please notice the output "no Server
is set! Skipping exploding war file ..." in the picture above)<br>
</code></p>
<p><code><br>

<p><code><img src="cid:part2.AC3F7308.6467AED9@linx-info.com" alt=""><br>
</code></p>
<p><br>
<code></code></p>
<p><br>
</p>
<p><br>
</p>
<p>my questions are that why does not the web page be open? it seem
as if ovirt-engine/webadmin/<wbr>WebAdmin.html does not be made, but I
do not know how to get the WebAdmin.html by maven command line,
Could you tell me that what is key point ?</p>
<p>In addition. I had ever attempt to 'mvn gwt:run' , but it did not
work, output is as following:</p>
<p>it tell me that the 'runTarget' is missing, but I don not know
how to get my 'runTarget'<br>
