I created a customized spring-boot starter project and want to deploy it to a remote maven repo. When I run mvn clean package deploy, I got an error said:
[ERROR] Failed to execute goal org.springframework.boot:spring-boot-maven-plugin:2.1.2.RELEASE:repackage (repackage) on project jcr-service-spring-boot-starter: Execution repackage of goal org.springframework.boot:spring-boot-maven-plugin:2.1.2.RELEASE:repackage failed: Unable to find main class -> [Help 1]

In fact, I don't think it is necessary for a spring-boot starter project to have got a main class, because it will never be run alone.
Could everyone help to explain how I can package the project please?
The error message mentions the usage of the Spring Boot Maven Plugin. The official documentation mentions:
The Spring Boot Maven Plugin provides Spring Boot support in Apache Maven. It allows you to package executable jar or war archives, run Spring Boot applications, generate build information and start your Spring Boot application prior to running integration tests.
Since you goal is to create a custom Spring Boot starter, there's no need to use the spring-boot-maven-plugin, so just remove it from your pom.xml and you should be able to package and deploy your jar.

I would like to build spring-boot 1.5.4.RELEASE. To do that I use the command
./mvnw clean install -U -Dmaven.test.skip=true -DskipTests=true
but I got the following problem (see below).
[ERROR] Failed to execute goal on project spring-boot-test: Could not resolve dependencies for project org.springframework.boot:spring-boot-test:jar:1.5.4.RELEASE: Could not find artifact org.springframework.boot:spring-boot:jar:tests:1.5.4.RELEASE in spring-ext (http://repo.spring.io/ext-release-local/) -> [Help 1]
How can I solve this issue?
I've been facing an issue with Maven SonarQube plugin (v2.6) when Maven version is recent (strictly larger than 3.1).
Here is what I run:
mvn clean verify -Psonar
mvn org.codehaus.mojo:sonar-maven-plugin:2.6:sonar -Psonar
The first invocation makes sure sources are compiled and JaCoCo agent is prepared.
The interesting part comes, when the second command is run:
[ERROR] Failed to execute goal org.codehaus.mojo:sonar-maven-plugin:2.6:sonar (default-cli) on project merlin-schema: Error setting Log implementation. Cause: java.lang.reflect.InvocationTargetException: org/slf4j/Marker -> [Help 1]
Any fix to be published?
Replacing default Maven logging implementation is currently not supported. Ticket created: http://jira.sonarsource.com/browse/MSONAR-122
I have a Java project where I want to make some calls to a Jung library. I added the following lines to the pom.xml
net.sf.jung
jung-algorithms
2.0.1
However when I run "mvn package", I get the following error
[ERROR] Failed to execute goal licensing-maven-plugin:1.
7.5:check (enforce-licensing-oss) on project server-examples: This project
has 3 disliked artifacts. -> [Help 1]
Any insights as to what may be going wrong ?
You have configured the licensing-maven-plugin to complain when you introduce a dependency with certain licenses. You, or whoever wrote your pom. If you read the configuration for that plugin it will tell you what licenses it is configured to like and dislike.
I am trying to create a JPA based project using Maven and eclipse. I tried using the jpa-maven-archetype from create new maven project in the eclipse project creation, but it shot back this error
Could not resolve archetype com.rfc.maven.archetypes:jpa-maven-archetype:RELEASE from any of the configured repositories.
Could not resolve artifact com.rfc.maven.archetypes:jpa-maven-archetype:pom:RELEASE

Basically the eclipse plugin is looking into my local repositories instead of remote ones. So I tried going the command line and explicitly specifying the remote repository with the following command
mvn org.apache.maven.plugins:maven-archetype-plugin:1.0-alpha-7:create \
-DgroupId=com.something -DartifactId=jpaexample \
-DarchetypeArtifactId=jpa-maven-archetype \
-DarchetypeVersion=RELEASE \
-DremoteRepositories=http://maven.rodcoffin.com/repo \
-DinteractiveMode=false
And I got this error

It seems that repo maven.rodcoffin.com/repo is not working, or there is something wrong with my maven setup. I am not sure which one, if some one could give me pointers on where to search for, that would be helpful.
Also if repo maven.rodcoffin.com/repo is not working. What are my other options to create a JPA archetype project. Do I have to make a simple maven project and then convert it to a JPA as shown here.
EDIT: I just weaseled out of the problem by creating a maven quick type achetype and then using the persistence.xml for my project.
So just ignore this question.
Anyone know how it can make a starting deploy the weblogic using Maven application settings? Maven weblogic already managed to insert the plugins and dependencies but contrary to the way I have had problems. Any tips?
