An alternative that worked for me is to tell Maven to use http: instead of https: when using Maven Central by adding the following to <a href="https://maven.apache.org/settings.html" rel="noreferrer">settings.xml</a>:

<pre><code>&lt;settings&gt;
 .
 .
 .
 &lt;mirrors&gt;
 &lt;mirror&gt;
 &lt;id&gt;central-no-ssl&lt;/id&gt;
 &lt;name&gt;Central without ssl&lt;/name&gt;
 &lt;url&gt;http://repo.maven.apache.org/maven2&lt;/url&gt;
 &lt;mirrorOf&gt;central&lt;/mirrorOf&gt;
 &lt;/mirror&gt;
 &lt;/mirrors&gt;
 .
 .
 .
&lt;/settings&gt;
</code></pre>

Your mileage may vary of course.

Create a folder <code>${USER_HOME}/.mvn</code> 
and put a file called <code>maven.config</code> in it.

The content should be:

<pre><code>-Dmaven.wagon.http.ssl.insecure=true
-Dmaven.wagon.http.ssl.allowall=true
-Dmaven.wagon.http.ssl.ignore.validity.dates=true
</code></pre>

Hope this helps.

blocks|key|4673005|text|我发现最新的jdk16将不能通过SSL证书，所以我不得不使用-Dmaven.wagon.http.ssl.ignore.validity.dates=true来解决；切换到jdk11(LTS)，然后所有的问题都消失了。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|4673006|也测试了jdk1.8，它在没有任何参数的情况下也可以工作；但是jdk1.8处于无更新模式，最好转移到LTS+jdk版本，而不是最新的jdk16。|4673007|entityMap^0|U|1D|0|0^^$0|@$1|2|3|4|5|6|7|J|8|@$9|K|A|L|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|M|8|@]|D|@]|E|$]]|$1|H|3|-4|5|6|7|N|8|@]|D|@]|E|$]]]|I|$]]

I found that the latest jdk16 will fail SSL certificates so I have to use the
<code>-Dmaven.wagon.http.ssl.ignore.validity.dates=true</code> to work around; switching to jdk11(LTS) then all problems are gone.
Also jdk1.8 was tested too, which also worked without any parameters; but jdk1.8 is in in no-update mode, better move on to the LTS jdk versions, but not the latest jdk16.

If you want to put all the same <code>maven.wagon.http.ssl.</code> settings into <code>~/.m2/settings.xml</code> instead of <code>~/.mavenrc</code>, this is what you need to put in the file:
<pre><code>&lt;settings xmlns=&quot;http://maven.apache.org/SETTINGS/1.0.0&quot; xmlns:xsi=&quot;http://www.w3.org/2001/XMLSchema-instance&quot;
 xsi:schemaLocation=&quot;http://maven.apache.org/SETTINGS/1.0.0 https://maven.apache.org/xsd/settings-1.0.0.xsd&quot;&gt;
 &lt;profiles&gt;
 &lt;profile&gt;
 &lt;id&gt;definedInM2SettingsXML&lt;/id&gt;
 &lt;activation&gt;
 &lt;activeByDefault&gt;true&lt;/activeByDefault&gt;
 &lt;/activation&gt;
 &lt;properties&gt;
 &lt;maven.wagon.http.ssl.insecure&gt;true&lt;/maven.wagon.http.ssl.insecure&gt;
 &lt;maven.wagon.http.ssl.allowall&gt;true&lt;/maven.wagon.http.ssl.allowall&gt;
 &lt;maven.wagon.http.ssl.ignore.validity.dates&gt;true&lt;/maven.wagon.http.ssl.ignore.validity.dates&gt;
 &lt;/properties&gt;
 &lt;/profile&gt;

I frequently need to run "mvn" command :

<pre><code>mvn -f pom.xml clean install -Dmaven.test.skip=false --settings /Users/myhome/settings.xml -X -Djavax.net.ssl.trustStore=/Users/myhome/truststore.jks -Djavax.net.ssl.trustStoreType=JKS -Djavax.net.ssl.trustStorePassword=dummy -Djava.protocol.handler.pkgs=com.sun.net.ssl.internal.www.protocol -U
</code></pre>

As I need to integrate with various other domains, so currently every time I have to add their certificate to my truststore.jks to prevent SSL handshake errors.

Is there any way I can configure mvn to ignore SSL errors.

How to tell Maven to disregard SSL errors (and trusting all certs)?
