How do I satisfy this requirement so that I can regain access to Central?

E.g:

org.ostermiller:utils:jar:1.07.00 (compile)]: Failed to read artifact descriptor for com.fasterxml.jackson.core:jackson-databind:jar:2.2.3: Could not transfer artifact com.fasterxml.jackson.core:jackson-databind:pom:2.2.3 from/to central (http://repo.maven.apache.org/maven2): Failed to transfer http://repo.maven.apache.org/maven2/com/fasterxml/jackson/core/jackson-databind/2.2.3/jackson-databind-2.2.3.pom. Error code 501, HTTPS Required

Solutions:

1. open your maven repository ${user.home}/.m2 folder and open the setting.xml if exist or else create a new one.

C:\Users\<user name\.m2

2. add the below entries in the setting.xml

<settings>
    <mirrors>
        <mirror>
          <id>centralhttps</id>
          <mirrorOf>central</mirrorOf>
          <name>Maven central https</name>
          <url>http://insecure.repo1.maven.org/maven2/</url>
        </mirror>
      </mirrors>
 </settings>

Fat Jar assembly using maven

1. pom.xml  add the below lines 

 <?xml version="1.0" encoding="UTF-8"?> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-assembly-plugin</artifactId> <executions> <execution> <id>make-bundles</id> <goals> <goal>single</goal> </goals> <phase>package</phase> <configuration> <descriptors> <descriptor>all-jar.xml</descriptor> </descriptors> <finalName>ct-mobile-service</finalName> <appendAssemblyId>false</appendAssemblyId> </configuration> </execution> </executions> </plugin>

1. <?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0"     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"     xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">     <modelVersion>4.0.0</modelVersion>     <parent>         <groupId>com.blujaysolutions.ct</groupId>         <artifactId>soa-ct-main</artifactId>         <version>1.0.0</version>         <relativePath>../soa-ct-main/pom.xml</relativePath>     </parent>     <artifactId>dist</artifactId>     <packaging>pom</packaging>     <name>Packaging Test : Distribution</name>     <properties>         <wildfly-home>D:\KCT\server\wildfly-17.0.0.Final</wildfly-home>         <wildfly-hostname>127.0.0.1</wildfly-hostname>         <wildfly-port>9990</wildfly-port>         <wildfly-username>Blujay</wildfly-username>         <wildfly-password>Bluj@y@123</wildfly-password>     </properties>     <dependencies>         <dependency>             <groupId>com.blujaysolutions.ct</groupId>             <artifactId>soa-ct-common</artifactId>             <version>${project.version}</version>         </dependency>         <dependency>             <groupId>com.blujaysolutions.ct</groupId>             <artifactId>soa-ct-dynamic-screen</artifactId>             <version>${project.version}</version>         </dependency>         <dependency>             <groupId>com.blujaysolutions.ct</groupId>             <artifactId>soa-ct-master-services</artifactId>             <version>${project.version}</version>         </dependency>         <dependency>             <groupId>com.blujaysolutions.ct</groupId>             <artifactId>soa-ct-mobile-service</artifactId>             <version>${project.version}</version>         </dependency>         <dependency>             <groupId>com.blujaysolutions.ct</groupId>             <artifactId>soa-ct-workflow-services</artifactId>             <version>${project.version}</version>         </dependency>         <dependency>             <groupId>com.blujaysolutions.ct</groupId>             <artifactId>soa-ct-swagger</artifactId>             <version>${project.version}</version>         </dependency>     </dependencies>     <build>         <plugins>             <plugin>                 <groupId>org.apache.maven.plugins</groupId>                 <artifactId>maven-assembly-plugin</artifactId>                 <executions>                     <execution>                         <id>make-bundles</id>                         <goals>                             <goal>single</goal>                         </goals>                         <phase>package</phase>                         <configuration>                             <descriptors>                                 <descriptor>all-jar.xml</descriptor>                             </descriptors>                             <finalName>ct-mobile-service</finalName>                             <appendAssemblyId>false</appendAssemblyId>                         </configuration>                     </execution>                     <execution>                         <id>make-bundles2</id>                         <goals>                             <goal>single</goal>                         </goals>                         <phase>package</phase>                         <configuration>                             <descriptors>                                 <descriptor>all-war.xml</descriptor>                             </descriptors>                             <finalName>ct-mobile-service</finalName>                             <appendAssemblyId>false</appendAssemblyId>                         </configuration>                     </execution>                 </executions>             </plugin>         </plugins>     </build> </project>

2. create the all-jar.xml to describe how to assemble the artifacts

<assembly xmlns="http://maven.apache.org/ASSEMBLY/2.0.0"     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"     xsi:schemaLocation="http://maven.apache.org/ASSEMBLY/2.0.0 http://maven.apache.org/xsd/assembly-2.0.0.xsd">     <id>bin</id>     <formats>         <format>jar</format>     </formats>     <includeBaseDirectory>false</includeBaseDirectory>     <dependencySets>         <dependencySet>             <includes>                 <include>${project.groupId}:*</include>             </includes>             <excludes>                 <exclude>io.springfox:*</exclude>                 <exclude>${project.groupId}:soa-ct-swagger:*</exclude>             </excludes>             <unpack>true</unpack>             <outputDirectory>.</outputDirectory>             <!-- <outputFileNameMapping>jolokia.war</outputFileNameMapping> -->         </dependencySet>         <!-- <dependencySet>             <outputDirectory>./dependencies</outputDirectory>             <excludes>                 <exclude>${project.groupId}:*:jar:*</exclude>                 <exclude>io.springfox:*:jar:*</exclude>             </excludes>         </dependencySet> -->     </dependencySets> </assembly>

3. now run the mvn clean package.
