maven build failing to download com.lowagie:itext:jar:2.1.7.js6 dependency

Previously my build is running fine but all of a sudden it's failing with the below error.
Failed to collect dependencies at ar.com.fdvs:DynamicJasper:jar:5.3.0 -> net.sf.jasperreports:jasperreports:jar:6.8.0 -> com.lowagie:itext:jar:2.1.7.js6: Failed to read artifact descriptor for com.lowagie:itext:jar:2.1.7.js6: Could not transfer artifact com.lowagie:itext:pom:2.1.7.js6 from/to maven-default-http-blocker (http://0.0.0.0/): Blocked mirror for repositories: [jaspersoft-third-party (http://jaspersoft.jfrog.io/jaspersoft/third-party-ce-artifacts/, default, releases+snapshots), jr-ce-releases (http://jaspersoft.jfrog.io/jaspersoft/jr-ce-releases, default, releases+snapshots)] -> [Help 1]

These are the dependencies I am using in my code.
<dependency>
<groupId>com.lowagie</groupId>
<artifactId>itext</artifactId>
<version>2.1.7.js6</version>
<scope>compile</scope>
</dependency>
<dependency>
<groupId>ar.com.fdvs</groupId>

<dependency>
<groupId>ar.com.fdvs</groupId>
<artifactId>DynamicJasper-core-fonts</artifactId>

</dependency>
I tried changing the DynamicJasper version also but no luck.
In the docker file, I am using the below image as a base image.
FROM maven:3.6.0-jdk-11-slim AS build

if you run maven on linux .then use this
<dependency>
<groupId>net.sf.jasperreports</groupId>
<artifactId>jasperreports</artifactId>
<version>6.12.1</version>
<exclusions>
<exclusion>
<groupId>com.lowagie</groupId>
<artifactId>itext</artifactId>
</exclusion>
</exclusions>
</dependency>
<!-- "jasperreports" can't resolve "itext" dependency on jenkins.so it added independently-->
<dependency>
<groupId>com.lowagie</groupId>
<artifactId>itext</artifactId>
<version>2.1.7</version>
</dependency>

<dependency>
<groupId>com.lowagie</groupId>
<artifactId>itext</artifactId>
<version>4.2.0</version>
</dependency>
My issue resolved after adding this dependency.

The modified versions of iText 2.1.7 are available on this public repository:
https://jaspersoft.jfrog.io/ui/native/third-party-ce-artifacts/com/lowagie/itext
Jars are available for downloading.

It looks like there is error in downloading com.lowagie:itext:pom:2.1.7.js6. I think there is a version number change in maven repository. there is not any 2.1.7.js6 version in maven repository.
<!-- https://mvnrepository.com/artifact/com.lowagie/itext -->
<dependency>
<groupId>com.lowagie</groupId>
<artifactId>itext</artifactId>
<version>2.1.7</version>
</dependency>
for your ref:
https://mvnrepository.com/artifact/com.lowagie/itext/2.1.7

Try to remove this dependency folder from users\.m2 folder and run maven install again. This will remove the old dependency which is causing issues and will download the same dependency again.

What is the dependancy for EmbeddedActiveMQBroker?

I'm new to Maven and not sure how to write dependancies for my pom.xml
I am trying to use the following class:
import org.apache.activemq.junit.EmbeddedActiveMQBroker;
And this is my attempt at writing a dependancy:
<dependency>
<groupId>org.apache</groupId>
<artifactId>activemq-junit</artifactId>
<version>5.15.9</version>
</dependency>
But I am still getting an error

Try with the following.
<dependency>
<groupId>org.apache.activemq.tooling</groupId>
<artifactId>activemq-junit</artifactId>
<version>5.13.1</version>
<scope>test</scope>
</dependency>
You can get the details from mvnrepository.com.

First of all we go to the official Maven Dependencies Page of ActiveMQ - https://mvnrepository.com/artifact/org.apache.activemq/activemq-broker/5.15.9.
Then, we go to the "Test Dependencies" category, where we clearly can see the JUnit artifact.
so, use in your pom.xml file next dependency for version 5.15.19:
<!-- https://mvnrepository.com/artifact/org.apache.activemq/activemq-broker -->
<dependency>
<groupId>org.apache.activemq</groupId>
<artifactId>activemq-broker</artifactId>
<version>5.15.9</version>
</dependency>
UPDATE
Add also the next dependency:
<!-- https://mvnrepository.com/artifact/org.apache.activemq.tooling/activemq-junit -->
<dependency>
<groupId>org.apache.activemq.tooling</groupId>
<artifactId>activemq-junit</artifactId>
<version>5.15.9</version>
<scope>test</scope>
</dependency>

How to include multiple jar in type from type field in pom dependency?

I have the following pom definition
<dependencies>
<dependency>
<groupId>com.my.stuff</groupId>
<artifactId>my-stuff</artifactId>
<version>${my-stuff.version}</version>
<type>test-jar</type>
</dependency>
I want to use both jar and test-jar , is there a way to do that?

I guess that test-jar is not a type, but a classifier. You probably want something like:
<dependencies>
<dependency>
<groupId>com.my.stuff</groupId>
<artifactId>my-stuff</artifactId>
<version>${my-stuff.version}</version>
<classifier>test-jar</classifier>
</dependency>
<dependency>
<groupId>com.my.stuff</groupId>
<artifactId>my-stuff</artifactId>
<version>${my-stuff.version}</version>
</dependency>
</dependencies>

Missing artifact error when adding a Maven dependency

I am not familiar with maven but I need to add a jnativehook dependency in a Java/Jersey project. I tried to add this dependency in my pom.xml
<dependency>
<groupId>com.1stleg</groupId>
<artifactId>system-hook</artifactId>
<version>2.0.3</version>
</dependency>
But I get an error on Eclipse
Missing artifact com.1stleg:system-hook:jar:2.0.3

According this, it should be:
<dependency>
<groupId>com.1stleg</groupId>
<artifactId>jnativehook</artifactId>
<version>2.0.3</version>
</dependency>
instead of
<dependency>
<groupId>com.1stleg</groupId>
<artifactId>system-hook</artifactId>
<version>2.0.3</version>
</dependency>
Hope it helps!

Automatic resolve dependency hierarchy for a custom jar

I am struggling with the maven dependencies. The maven dependency hierarchy is not resolved in my projects where I add my custom build jar. This is a little bit confusing, because all the dependencies of other externally provided dependencies (like org.json, reasteasy-jaxrs ) are nicely shown in the dependency hierarchy view.I am using Eclipse EE IDE for Web Developers with maven plugin.
The project structure: The project is a platform consisting of several services using the same project-support module. Further, the project-support will be used in external projects (here project-consumer) as well.
project-parent (pom)
project-support (jar)
project-service-a (war)
project-service-b (jar)
project-consumer (war)
project support (jar)
Extract of project-parent.pom
<modules>
<module>../project-support</module>
<module>../project-serviceA</module>
<module>../project-serviceB</module>
</modules>
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<tomcat.version>7.0.50</tomcat.version>
</properties>
<dependencyManagement>
<dependencies>
<dependency>
<groupId>org.apache.tomcat</groupId>
<artifactId>tomcat-catalina</artifactId>
<version>${tomcat.version}</version>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>org.codehaus.jackson</groupId>
<artifactId>jackson-mapper-asl</artifactId>
<version>1.6.3</version>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>org.json</groupId>
<artifactId>json</artifactId>
<version>20140107</version>
<scope>provided</scope>
</dependency>
</dependencies>
</dependencyManagement>
Extract of project-support.pom
<parent>
<groupId>com.somecompany.project</groupId>
<artifactId>project-parent</artifactId>
<version>1.1.0-SNAPSHOT</version>
<relativePath>../project-parent</relativePath>
</parent>
<artifactId>project-support</artifactId>
<name>projectsupport</name>
<dependencies>
<dependency>
<groupId>org.apache.tomcat</groupId>
<artifactId>tomcat-catalina</artifactId>
</dependency>
<dependency>
<groupId>org.codehaus.jackson</groupId>
<artifactId>jackson-mapper-asl</artifactId>
</dependency>
<dependency>
<groupId>org.json</groupId>
<artifactId>json</artifactId>
</dependency>
</dependencies>
Extract of project-service-a.pom
<parent>
<groupId>com.somecompany.project</groupId>
<artifactId>project-serviceA</artifactId>
<version>1.1.0-SNAPSHOT</version>
<relativePath>../project-parent</relativePath>
</parent>
<artifactId>project-service-a</artifactId>
<name>projectsupport</name>
<dependencies>
<dependency>
<groupId>com.somecompany.project</groupId>
<artifactId>project-support</artifactId>
</dependency>
<dependency>
<groupId>org.quartz-scheduler</groupId>
<artifactId>quartz</artifactId>
<version>2.2.1</version>
</dependency>
</dependencies>
So, when looking at the project-serviceA dependency hierarchy (and also in the effective pom), the required dependencies of project-support are not included which results in code compilation errors. Further the project-support is used in projects outside the scope of project-parent.
So my question: Why does maven not resolve the dependencies tree of project-support and adds them into the effective pom?
Thanks in advance.

You have set the scope of the dependencies to provided in you parent's dependency management section. According to the introduction to the dependency mechanism, the dependency scope is used to limit the transitivity of a dependency.
The above linked introduction also includes a table that declares which scopes play in the transitivity game and which do not. The provided scope is not part of the transitivity.
So the solution is to not declare any scope in the dependency management but declare a reasonable scope in the dependency usage.
