I need to integrate this dependency within my maven project:
<!-- https://mvnrepository.com/artifact/org.apache.beam/beam-sdks-java-io-google-cloud-platform -->
<dependency>
<groupId>org.apache.beam</groupId>
<artifactId>beam-sdks-java-io-google-cloud-platform</artifactId>
<version>2.11.0</version>
</dependency>
However, when I try to execute the command mvn verify within my project I get the error attached:
thanks for the help!
Update
I have included my pubsub dependency like:
<dependency>
<groupId>com.google.cloud</groupId>
<artifactId>google-cloud-pubsub</artifactId>
<version>1.69.0</version>
<exclusions>
<exclusion>
<groupId>io.grpc</groupId>
<artifactId>grpc-core</artifactId>
</exclusion>
</exclusions>
</dependency>
The functions offered by Beam are not suitable for my project unfortunately.
What you are describing is the Diamond Dependency problem.
If you can use the same version of pubsub as beam you should not have this conflict. Per Maven Central, beam-sdks-java-io-google-cloud-platform depends on grpc-google-cloud-pubsub-v1 1.43.0.
I have figure it out the point is that I had on my pom.xml the dependency :
<!-- <dependency>-->
<!-- <groupId>com.google.cloud</groupId>-->
<!-- <artifactId>google-cloud-pubsub</artifactId>-->
<!-- <version>1.66.0</version>-->
<!-- </dependency>-->
But then how should I do if I need to work with these two dependencies on the same project?

Maven shade plugin is very powerful for resolving dependency conclict, but a situation I have is as follows :
myproject
guava 31
thridparty-dependency-1
guava18
I could relocate the guava 31 dependency and then the conflict will be resolved. And how about following situation :
myproject
thirdparty-1
guava31
thirdparty-2
guava18
thirdparty-3
guava4
Or how about if there are more than two dependencies conflicting as the same dependency but with different versions ?
If I use relocation, then thirdparty-1/guava31 will be relocated but the guava18 and guava4 still conflict.
I'm not sure how to handle this situation.
You need to de-conflict these across the whole project, not just for the shaded uber-jar.
Use Maven <exclusions> in the pom.xml declarationtion to achieve this.
For example:
<dependency>
<groupId>org.neo4j</groupId>
<artifactId>neo4j</artifactId>
<version>${neo4j.version}</version>
<exclusions>
<exclusion>
<groupId>io.netty</groupId>
<artifactId>netty-transport-native-epoll</artifactId>
</exclusion>
</exclusions>
</dependency>
<dependency>
<groupId>io.netty</groupId>
<artifactId>netty-transport-native-epoll</artifactId>
<version>${netty.version}</version>
</dependency>
Despite having appropriate jars in classpath Spring Boot throws - java.lang.ClassNotFoundException: org.apache.camel.spring.spi.XmlCamelContextConfigurer
Any suggestions what is missing here.
I have added the respective starters in pom.xml as shown below:
<dependency>
<groupId>org.springframework.boot</groupId>[![enter image description here][1]][1]
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
<groupId>org.apache.camel</groupId>
<artifactId>camel-cxf</artifactId>
<version>2.19.3</version>
</dependency>
The project maven dependencies also shows the class availability, as in given image attachment.
the answer is here - https://stackoverflow.com/a/34271507/2885422 It all depends how maven loads the class. There are 2 version of camel-spring.jars available in classpath (2.20.1 and 2.19.3. Ref: my original post image)
And org.apache.camel.spring.spi.XmlCamelContextConfigurer class is available only in 2.20.1 jars. And maven by default looks in earlier one and once package found matching but no class found throws error (?)
And the reason I believe 2.19.3 get loaded is Apache-cxf jars is of 2.19.3. Unfortunately our project repository does not have apache-cxf starter jars.

Solution: - I hope it may be helpful for future references
By adding options I could resolve the issue,by having exclusion clause added as given below. Thus I could load only required version jars.
<dependency>
<groupId>org.apache.camel</groupId>
<artifactId>camel-cxf</artifactId>
<version>2.19.3</version>
<exclusions>
<exclusion>
<groupId>org.apache.camel</groupId>
<artifactId>camel-spring</artifactId>
</exclusion>
<exclusion>
<groupId>org.apache.camel</groupId>
<artifactId>camel-core</artifactId>
</exclusion>
</exclusions>
</dependency>'
Caused by:
java.lang.IncompatibleClassChangeError: Class com.ibm.wsdl.DefinitionImpl does not implement the requested interface javax.wsdl.extensions.AttributeExtensible
The reason for axis-wsdl4j-1.5.1.jar getting downloaded when you try and build using axis:1.4 in your project is that it is defined within dependency for the artifact itself..
If you don't want to download axis-wsdl4j-1.5.1.jar, you can exclude it from your project by making following changes to your pom.xml -
<dependencies>
<dependency>
<groupId>axis</groupId>
<artifactId>axis</artifactId>
<version>1.4</version>
<exclusions>
<exclusion> <!-- declaring the exclusion here -->
<groupId>axis</groupId>
<artifactId>axis-wsdl4j</artifactId>
</exclusion>
</exclusions>
</dependency>
<!--...other dependencies -->

I would like to use the logback slf4j implementation in my application, but activemq-all is spoiling the classpath by including the log4j implementation classes. I'm not the only one facing that problem, as witnessed by for instance multiple SLF4J bindings Error with activemq-all-5.6.0.jar. According to that post I have to replace activemq-all by
org.apache.activemq:activemq-camel
org.apache.activemq:activemq-core
org.apache.activemq:activemq-console
org.apache.activemq:activemq-jaas
org.apache.activemq:activemq-optional
org.apache.activemq:kahadb
org.apache.geronimo.specs:geronimo-jms_1.1_spec
org.apache.geronimo.specs:geronimo-jta_1.0.1B_spec
org.apache.geronimo.specs:geronimo-j2ee-management_1.1_spec
org.apache.geronimo.specs:geronimo-annotation_1.0_spec.
The problem is that I don't have the complete maven dependencies (group id, artifact id, version) for these artifacts. Can someone provide me with a ready-to-use replacement for
<dependency>
<groupId>org.apache.activemq</groupId>
<artifactId>activemq-all</artifactId>
<version>5.9.0</version>
</dependency>
You can use active mq core library. Please note that active mq is backward compatible for client.
<dependency>
<groupId>org.apache.activemq</groupId>
<artifactId>activemq-core</artifactId>
<version>5.4.3</version>
<exclusions>
<exclusion>
<artifactId>org.slf4j</artifactId>
<groupId>slf4j-log4j12</groupId>
</exclusion>
<exclusion>
<artifactId>log4j</artifactId>
<groupId>log4j</groupId>
</exclusion>
</exclusions>
</dependency>
In a nutshell, you have already listed group id/artifact id separated by a colon for the artifact you found. Please note that these satisfy some usecase with ActiveMQ 5.6. For instance activemq-core is not really valid any more - use activemq-client and activemq-broker instead.
Currently, these artifact are bundled in activemq-all. But you may want to check out the pom.xml for your version of choice (this list might change over time). You probably won't need all of them unless you are about to embedd a broker with all transports, plugins and configurations within your applications.

Ok, the version number for org.apache.activemq should simply be the release you want to use. For the geronimo specs, this is not so obvious.
<dependency>
<groupId>org.apache.geronimo.specs</groupId>
<artifactId>geronimo-jms_1.1_spec</artifactId>
<version>1.1.1</version>
</dependency>
<dependency>
<groupId>org.apache.geronimo.specs</groupId>
<artifactId>geronimo-j2ee-management_1.1_spec</artifactId>
<version>1.0.1</version>
</dependency>
<dependency>
<groupId>org.apache.geronimo.specs</groupId>
<artifactId>geronimo-annotation_1.0_spec</artifactId>
<version>1.1.1</version>
</dependency>
I was also facing this same issue with activemq-all API and I replaced this dependency with this below dependency and it worked for me.
<!-- https://mvnrepository.com/artifact/org.apache.activemq/activemq-spring -->
<dependency>
<groupId>org.apache.activemq</groupId>
<artifactId>activemq-spring</artifactId>
<version>5.14.3</version>
</dependency>
Hope this can help others.
How can I remove artifacts from the lib folder of the ear? For exemple: activation.jar.
I was try follow the especification about Excluding a module (just change webModule for jarModule) but without success with this error: Artifact[jar:javax.activation:activation] is not a dependency of the project.
Use provided as scope wherever the dependency is defined.
<dependency>
<groupId>javax.activation</groupId>
<artifactId>activation</artifactId>
<version>1.1.1</version>
<scope>provided</scope>
</dependency>
Set the scope to provided. Maven will still add the dependency to the compile time classpath but not to the final WAR.
As others have said, you need to use provided as the scope. If the jars you need to remove are not dependencies of your project directly (ie are transient dependencies), then you need to exclude them from whatever is bringing them into your build . If you actually need those classes at compile-time, you'll have to re-include them as provided:
<dependency>
<!-- this dependency has javax.activation as a dependency -->
<groupId>blah.groupId</groupId>
<artifactId>blah.artifactId</artifactId>
<version>blah.version</version>
<exclusions>
<exclusion>
<groupId>javax.activation</groupId>
<artifactId>activation</artifactId>
<exclusion>
</exclusions>
</dependency>
<!-- only necessary if this jar is needed at compile-time -->
<dependency>
<groupId>javax.activation</groupId>
<artifactId>activation</artifactId>
<version>1.1.1</version>
<scope>provided</scope>
</dependency>
