Unable to integrate Hazelcast version 4.2 with Spring Boot 2.3.6.RELEASE

I am using Spring Boot version 2.3.6.RELEASE in my application and added hazelcast version 4.2 and wanted to use spring-integration-hazelcast of version 3.0.0 as this only is compatible with hazelcast 4.2 version.
But getting below error during build:
Require upper bound dependencies error for org.springframework.integration:spring-integration-core:5.3.4.RELEASE paths to dependency are:
+-package:ocapi-admin-service:4.0.0-SNAPSHOT
+-org.springframework.integration:spring-integration-core:5.3.4.RELEASE
and
+-package:ocapi-admin-service:4.0.0-SNAPSHOT
+-org.springframework.integration:spring-integration-hazelcast:3.0.0
+-org.springframework.integration:spring-integration-core:5.3.4.RELEASE (managed) <-- org.springframework.integration:spring-integration-core:5.4.0
]
Below is the pom snippet:
<dependency>
<groupId>org.springframework.integration</groupId>
<artifactId>spring-integration-core</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.integration</groupId>
<artifactId>spring-integration-hazelcast</artifactId>
<version>3.0.0</version>
</dependency>
<dependency>
<groupId>com.hazelcast</groupId>
<artifactId>hazelcast</artifactId>
<version>4.2</version>
</dependency>
<dependency>
<groupId>com.hazelcast</groupId>
<artifactId>hazelcast-spring</artifactId>
<version>4.2</version>
</dependency>

I think you need to update the version of spring-integration-core to at least 5.4.0.
You don't specify it in the code snippet from pom.xml you shared, but I guess it must be taken from somewhere else since you have it in the logs. Try changing this dependency to the following one:
<dependency>
<groupId>org.springframework.integration</groupId>
<artifactId>spring-integration-core</artifactId>
<version>5.4.0</version>
</dependency>

Resteasy 2.3.10.Final ClientResponse.readEntity AbstractMethodError

I am currently trying to create a Resteasy Client, having to use Version 2.3.10.Final. Unfortunately, I should not use a newer Version. I am very new to this, so I hope I manage to provide all required Information to make this question answerable.
First, the Request is created and finally "PUT". The returned ClientResponse is to be evaluated.
I can successfully call
Response.getStatus()
showing me that the "PUT" has been successful, as the Status is equal to
Response.Status.CREATED.getStatusCode()
However, any attempt to call response.readEntity Returns the error
java.lang.AbstractMethodError: javax.ws.rs.core.Response.readEntity(Ljava/lang/Class;)Ljava/lang/Object;
at blabla.evaluateResponse(MyResteasyClient.java:80)´
This is for any attempt to call .readEntity, but for the sake of specificity, let's concentrate on
String entity = Response.readEntity(String.class);
When attempting response.getEntity(), it Returns the following error message:
java.lang.RuntimeException: RESTEASY001555: No type information to extract entity with, use other getEntity() methods
at org.jboss.resteasy.client.core.BaseClientResponse.getEntity(BaseClientResponse.java:337)
at blabla.evaluateResponse(MyResteasyClient.java:81)
Am I even on the right Track? My Goal is to achieve something along the lines of:
List<? extends MyResponse> myResponses = response.readEntity(new GenericType<List<MyResponse>>() {});
Where the class "MyResponse" is an implementation of the Interface
public interface MyPartialResponse {
boolean isSuccessful();
String getMessage();
}
The dependencies within pom.xml are:
<properties>
<version.jackson>2.6.5</version.jackson>
<version.resteasy-client>2.3.10.Final</version.resteasy-client>
</properties>
<dependencies>
(removed a company specific dependency)
<dependency>
<groupId>org.jboss.resteasy</groupId>

<version>${version.resteasy-client}</version>

<version>3.6</version>
</dependency>
</dependencies>

If anyone happens to land on this question with the same error, let me provide the answer, how I solved my issue:
By adding
BaseClientResponse<?> r = (BaseClientResponse<?>) response;
I could successfully call
r.getEntity(new GenericType<List<MyResponse>>() {});

I think there is a conflicts between Jar files in Maven. Please check your maven dependency hierarchy.

I have observed this problem with Netty version 4.1.15.Final but not with 4.1.13.Final. Check your transitive dependencies. I.e Spring Boot references Netty.
What I added to POM to make it work with Spanner API version 0.22.0-beta:
<properties>
<v.netty>4.1.13.Final</v.netty>

If the problem persists, or if it is not an option, plase run your JVM with appropriate bootclasspath entry, like:
java -Xbootclasspath/p:/tmp/alpn-boot-8.1.11.v20170118.jar -cp ...
Make sure to replace /tmp/alpn-boot-8.1.11.v20170118.jar with location of alpn jar that matches your JVM version as listed on this page: https://www.eclipse.org/jetty/documentation/9.4.x/alpn-chapter.html

There is a possible solution on github: "Exception when configuring SSL: "Jetty ALPN/NPN has not been properly configured."
The recommended steps, quoting from the above document:
1) Edit catalina.sh
/usr/local/Cellar/tomcat/8.5.3/libexec/bin/catalina.sh
2) At line 103, add the following
CATALINA_OPTS="-javaagent:/Library/Tomcat/lib/jetty-alpn-agent-2.0.6.jar"
3) Restart tomcat
../bin/shutdown.sh ../bin/startup.sh

Maven cannot load dependency from another dependency in repository

I am new to Maven, I try to load tranquility using the following in pom.xml:
<dependency>
<groupId>io.druid</groupId>
<artifactId>tranquility-core_2.11</artifactId>
<version>0.7.0</version>
</dependency>
Then I get an error: Failure to find com.fasterxml.jackson-module-scala_2.11:jar:2.4.6.
I tried to search in search.maven.org, and find out that, inside the io.druid tranquility-core module, the dependency is:
<dependency>
<groupId>com.fasterxml.jackson.module</groupId>
<artifactId>jackson-module-scala_2.11</artifactId>
<version>2.4.6</version>
</dependency>
However, when I try to search Jackson-module-scala_2.11 in the central repository, there's no 2.4.6 version there, there's only 2.4.5 and 2.5.0. See the following link: http://search.maven.org/#search|gav|1|g%3A%22com.fasterxml.jackson.module%22%20AND%20a%3A%22jackson-module-scala_2.11%22
So is there a way for me to build it successfully even the module in central repository (in this case the tranquility module) makes mistake in referencing another module?
Thanks.

you can exclude the dependency in the io.druid tranquility, and dependency it by yourself with the exist version like this:
<dependency>
<groupId>io.druid</groupId>
<artifactId>tranquility-core_2.11</artifactId>
<version>0.7.0</version>
<exclusions>
<exclusion>
<groupId>com.fasterxml.jackson.module</groupId>
<artifactId>jackson-module-scala_2.11</artifactId>
</exclusion>
</exclusions>
</dependency>
<dependency>
<groupId>com.fasterxml.jackson.module</groupId>
<artifactId>jackson-module-scala_2.11</artifactId>
<version>2.5.0</version>
</dependency>

Correct set of dependencies for using Jackson mapper

I am new to Jackson and I was writing some code for practice. I found out the the new version of Jackson library can be found on Fasterxml: Jackson, so I added the below dependencies to my Maven pom file:
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-annotations</artifactId>
<version>2.2.2</version>
</dependency>
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-core</artifactId>
<version>2.2.2</version>
</dependency>
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-databind</artifactId>
<version>2.2.2</version>
</dependency>
I was expecting that I can use the ObjectMapper directly, however after spending a lot of time I found out that to use the ObjectMapper I have to add the old libraries below:
<dependency>
<groupId>org.codehaus.jackson</groupId>
<artifactId>jackson-mapper-asl</artifactId>
<version>1.9.2</version>
</dependency>
<dependency>
<groupId>org.codehaus.jackson</groupId>
<artifactId>jackson-core-asl</artifactId>
<version>1.9.2</version>
</dependency>
I am a bit confused. Could someone please tell me why is that?

<properties>
<!-- Use the latest version whenever possible. -->
<jackson.version>2.4.4</jackson.version>
</properties>
<dependencies>
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-databind</artifactId>
<version>${jackson.version}</version>
</dependency>
</dependencies>
you have a ObjectMapper (from Jackson Databind package) handy.
if so, you can do:
JsonFactory factory = objectMapper.getFactory();
Source: https://github.com/FasterXML/jackson-core
So, the 3 "fasterxml" dependencies which you already have in u'r pom are enough for ObjectMapper as it includes jackson-databind.

No, you can simply use com.fasterxml.jackson.databind.ObjectMapper.
Most likely you forgot to fix your import-statements, delete all references to codehaus and you're golden.

The package names in Jackson 2.x got changed to com.fasterxml1 from org.codehaus2. So if you just need ObjectMapper, I think Jackson 1.X can satisfy with your needs.

I spent few hours on this.
Even if I had the right dependency the problem was fixed only after I deleted the com.fasterxml.jackson folder in the .m2 repository under C:\Users\username.m2 and updated the project

Apart from fixing the imports, do a fresh maven clean compile -U. Note the -U option, that brings in new dependencies which sometimes the editor has hard time with. Let the compilation fail due to un-imported classes, but at least you have an option to import them after the maven command.
Just doing Maven->Reimport from Intellij did not work for me.
