Dirty work: Maven issue to JFrog

Recently, I found a trouble I used maven with JFrog.

Actually at home, I can easily use Maven to get what libraries I want remotely.

However, in company, I cannot do that.

As a several experiences for Gradle. I bet proxy is the issue.

Cannot connect to repo.maven.apache.org/maven2/

I tried many setting in pom.xml. But all failed.

Finally I found setting.xml is my hero!

The location of setting.xml is in ~/.m2 , it is not easy to know it.

When we find setting.xml file, we can solve the problem easily.

<proxies>
    <proxy>
        <id>optional</id>
        <active>true</active>
        <protocol>http</protocol>
        <host><company proxy></host>
        <port>8080</port>
        <nonProxyHosts><company proxy></nonProxyHosts>
    </proxy>
</proxies>

If you have username or password for proxy, just type it.

And we will solve the issue.

a “401 Unauthorized” error when I deploy in Maven?

It clearly caused by username and password.

However how do we set them?

Also, setting.xml is our best friend.

in ~/.m2/setting.xml , just edit the following:

<servers>
    <server>
        <id>snapshots</id>
        <username>$username</username>
        <password>$password</password>
    </server>
    <server>
        <id>releases</id>
        <username>$username</username>
        <password>$password</password>
    </server>
</servers>

Notice: the id must be both of them

$username and $password is the username and password for our JFROG!

In the end, we will solve the issue!
