Solved this by adding the self signed certificate of my company to the cacerts file of Android Studio. The cacerts file is located here: <code>C:\Program Files\Android\Android Studio\jre\jre\lib\security\cacerts</code> 

I have also added the proxy details for http/https to gradle.properties.

blocks|key|991104|text|有时，只需升级到最新的gradle包装器(+gradle+-wrapper.properties)和gradle插件(主build.gradle+->+buildscript+->依赖项->+com.android.tools.build:gradle)就会有所帮助。如果您正在加载多个项目，并且已经更新了其中的一个项目，则尤其如此。我这样做了，突然我的“其他”项目就不同步/构建了。更新它们也解决了这个问题。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|991105|值得注意的是，我们公司确实有一个非常封闭的网络，有大量的流量嗅探和证书重写，所以这可能是问题的最初原因。即使将自签名证书添加到Android的“认可”证书列表中，我在做上述工作之前仍然存在问题。以前，我甚至看到了终端中的构建(./gradlew+assembleDebug，它工作得更频繁)和在Android中构建(工作频率较低)之间的区别。|991106|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|$]]

Sometimes it helps to just upgrade to the latest gradle wrapper (gradle-wrapper.properties) and gradle plugin (main build.gradle -> buildscript -> dependencies -> com.android.tools.build:gradle). This is especially true if you're loading multiple projects and you've updated one of them. I did that and suddenly my "other" projects wouldn't sync/build. Updating them as well resolved that issue.

It bears noting that our company does have a very locked down network with tons of traffic sniffing and cert rewriting so that's likely the initial cause of the issue. Even with adding the self-signed certs into Android Studio's "approved" certificate list, I was still having issues until I did the above. Previously, I've even seen a difference between building in the terminal (./gradlew assembleDebug, which worked more often) and building in Android studio (which worked less often).

Yeah, I have resolved the issue by changing the WiFi network connection. do any of the following step
1. connect to other or Mobile network(use hotspot) and reconnect to WiFi network
2. Reset your wifi network in laptop

lets resolved this issue so
go to the stack trace and see the first url of your stack trace where issue is pointed like in this post
<pre><code>https://dl.google.com/dl/android/maven2/com/android/support/appcompat-v7/26.1.0/appcompat-v7-26.1.0.pom
</code></pre>
in your browser: but before that strip the last <code>.pom</code> or <code>/filename.extension</code> from your url.
<ul>
<li>in chrome - click on site of url icon left(<code>lock icon</code> in general) to address in address bar,
</li>
<li>select <code>&quot;Certificate&quot; -&gt; &quot;Certification Path&quot;-&gt;</code>select root node like <code>&quot;Corp-Prj-Root-CA&quot;-&gt; &quot;View Certificate&quot; -&gt; &quot;Details&quot; -&gt; &quot;Copy to File...&quot;</code> and save in the format of <code>&quot;Der-encoded binary X.509(.CER)&quot;</code> single certificate file let name it <code>rootCertFile.cer</code>.
</li>
<li>Now you have file with keystore and you have to add it to your JVM. To Determine location of <code>cacerts</code> files eg. <code>C:\Program Files (x86)\Java\jre1.6.0_22\lib\security\cacerts</code>.
</li>
<li>or check your android studio Java Path in <code>Project settings</code>
</li>
</ul>
Next import the <code>rootCertFile.cer</code> file into cacerts
<blockquote>
Solution1
</blockquote>
using <code>keytool</code> in command line (you need to run as administrator command prompt):
<pre><code>keytool -import -alias example -keystore &quot;C:\Program Files (x86)\Java\jre1.6.0_22\lib\security\cacerts&quot; -file rootCertFile.cer
</code></pre>
You will be asked for password by default it is <code>changeit</code>
<blockquote>
Solution2
</blockquote>
you can use the <a href="https://keystore-explorer.org/downloads.html" rel="nofollow noreferrer">keyExplorer software</a> run as administrator and open the <code>yourjavapath-&gt; jre-&gt;lib-&gt;security-&gt; cacerts</code> file as per android studio path in it and
<ul>
<li>it will asked for password by default it is <code>changeit</code> enter then
</li>
<li>click on the <code>&quot;Import Trusted certificate&quot;</code> icon or from <code>Tools</code> option and give the path of above saved certificate name <code>rootCertFile.cer</code>
</li>
<li>then it will as for <code>alias name</code> give some unique name and press <code>ok</code> and
</li>
<li>click on the <code>save icon</code>
</li>
<li>also make sure about the proxy setting if any from company depend on certificate then that certificate also we need to add in same way
</li>
<li>and we are done <code>delete android studio caches directory</code> and now try <code>gradle sync</code> in your project
</li>
</ul>

I fixed this issue by adding below script code in root build.gradle under buildscript tag
<pre><code>repositories {
 maven {
 url &quot;https://jitpack.io&quot;
 }
 maven {
 url &quot;https://raw.github.com/Raizlabs/maven-releases/master/releases&quot;
 }
 maven {
 url &quot;http://oss.sonatype.org/content/repositories/snapshots&quot;
 allowInsecureProtocol = true
 }
 maven {
 url &quot;https://jcenter.bintray.com&quot;
 allowInsecureProtocol = true
 }
 maven {
 url &quot;https://plugins.gradle.org/m2/&quot;
 }
 maven {
 url &quot;https://maven.google.com&quot;
 }
 google()
 jcenter()
 }
</code></pre>
The key is to add
<blockquote>
allowInsecureProtocol = true
</blockquote>
