Weird issue running maven site (problems were encountered while processing the POMs)

Weird issue running maven site (problems were encountered while processing the POMs) - java

I'm trying to run mvn site but I keep getting this error message every time. I've tried googling, but have not found any solutions. I'm currently on a Windows machine running maven from git bash.
[WARNING] Unable to create Maven project for org.crashub:crash.shell:pom:1.3.1 from repository.
org.apache.maven.project.InvalidProjectModelException: Some problems were encountered while processing the POMs:

I have found these 2 related issues:
https://jira.exoplatform.org/browse/CRASH-225
https://jira.codehaus.org/browse/MSHADE-185
So the cause seems to be in the Maven Shade Plugin: the CRaSH POM seems to use the Shade Plugin and then has the wrong, hardcoded systemPath.
According to http://www.crashub.org/:
CRaSH is officially embedded as Spring Boot remote shell.
So org.crashub:crash.shell:pom:1.3.1 seems to be related to Spring Boot, but I don't know what is meant by the warning: "Unable to create Maven project for [...]"
EDIT
Try to add the following dependency to your POM:
<dependency>
<groupId>com.sun</groupId>
<artifactId>tools</artifactId>
<version>1.8</version>
<scope>system</scope>
<systemPath>${java.home}/../lib/tools.jar</systemPath>
<optional>true</optional>
</dependency>

SpringBoot Application fails startup when adding dependency

I have an existing SpringBoot Application that was running with no issue. I then created a Java library—a standalone repository with only static Java code, no main class. My library is deployed as a GitHub Maven package.
I then proceeded with setting up my GitHub packages repository in my local Maven settings and added the dependency to my original SpringBoot application. The import process is successful, my library's Jar is in the classpath and compilation and build are successful.
What happens next is I run the application now, and I get the following stacktrace:
02:36:51.110 [main] DEBUG org.springframework.boot.context.logging.ClasspathLoggingApplicationListener - Application failed to start with classpath: [<redacted list of classpath dependencies, including my new library>]

I'm not sure what else to try and a night of Googling lead me nowhere.

Thanks much.
Edit: set spring-boot-starter-parent version in application pom to match the version in the library pom. No changes.

You're using different versions of spring-boot-starter-parent (2.3.1.RELEASE and 2.3.4.RELEASE) which is probably leading to inconsistent versions where the later or earlier don't have the method. Try using 2.3.4.RELEASE in your application.
[Update]
You're still getting inconsistent versions of org.springframework:* on the classpath:
[INFO] | \- org.springframework:spring-webmvc:jar:5.2.9.RELEASE:compile
[INFO] | +- org.springframework:spring-aop:jar:5.2.9.RELEASE:compile
[INFO] | \- org.springframework:spring-expression:jar:5.2.9.RELEASE:compile
...
[INFO] +- org.springframework:spring-web:jar:5.2.7.RELEASE:compile
In your application pom.xml remove the explicit dependency from
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-web</artifactId>
<version>5.2.7.RELEASE</version>
</dependency>
and any other dependency that is specified in the parent so you get all 5.2.9 versions in the dependency output.
Finally, there is discussion like here about requiring specific versions for Spring Boot and the latest version of spring-cloud-aws-secrets-manager-config is 2.2.4.RELEASE which makes me think your library's POM needs to be updated to use the latest.

How to use in Eclipse Maven with Log4j2? [duplicate]

I'm getting this error trying to use log4j2 with spring boot.
ERROR StatusLogger Log4j2 could not find a logging implementation.
Please add log4j-core to the classpath. Using SimpleLogger to log to the console...
I'm have followed this guide: http://docs.spring.io/spring-boot/docs/current/reference/html/howto-logging.html#howto-configure-log4j-for-logging - and also added the two log4j2-dependencies from https://logging.apache.org/log4j/2.x/maven-artifacts.html
My dependency:tree looks like this:

Any guesses? I've tried running from within Spring Tool Suite and with the maven spring-boot plugin.

I looked up the source code of LogManager.class and found the reason was there's no LoggerContextFactory found in log4j-provider.properties which should be found in log4j-core.jar/META-INF.
So check your log4j-core.jar/META-INF/log4j-provider.properties file , or you can delete your log4j-core.jar in your local repository.

It looks your dependencies are correct. This is the pom of working spring-boot application with log4j2 as logging framework:
<!-- Spring logging -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter</artifactId>
<exclusions>
<exclusion>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-logging</artifactId>
</exclusion>
</exclusions>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-log4j2</artifactId>
</dependency>
Put your log4j2.xml into resource folder for running from eclipse; if you prefer to use the different directory - resource/conf - provide the path to log4j2 configuration with JVM argument like this:
-Dlog4j.configurationFile=”conf/log4j2.xml”
Do not give up and switch back from logback to log4j2...

That error message is generated by the log4j-api module when it cannot find or load an implementation of its interfaces. Usually this means that the log4j-core module is missing from the classpath, but looking at your dependency graph that doesn't seem to be the case.
There are some transitive dependencies on the log4j-slf4j-impl and log4j-jul modules but I don't think that could cause the error message.
One way to investigate further is to try starting your application again with this system property set: -Dorg.apache.logging.log4j.simplelog.StatusLogger.level=TRACE. This will print log4j internal debug logging to the console.
(Once your configuration file is loaded the StatusLogger output level can be controlled by setting <Configuration status="trace"> in the beginning of the log4j2.xml configuration file. However, the configuration file is loaded by the log4j-core module, and we're not there yet...)

There might be multiple reasons but common reason is you might have wrong JAR (corrupted).
Delete JARs from repository and try to download again. It will solve the problem.
In my case I have deleted org folder from maven repository
{home}.m2\repository\org.
I have posted similar question here.
Spring boot: ERROR StatusLogger Log4j2 could not find a logging implementation

Adding below setting solved my issue.
-Dlog4j2.loggerContextFactory=org.apache.logging.log4j.core.impl.Log4jContextFactory

A required class was missing while executing org.eclipse.jetty:jetty-maven-plugin:9.2.3.v20140905:run: javax/ws/rs/client/RxInvokerProvider

I keep on getting this error message:
A required class was missing while executing org.eclipse.jetty:jetty-maven-plugin:9.2.3.v20140905:run: javax/ws/rs/client/RxInvokerProvider
I have tried to remove the maven repo so that it is forced to download the library again, but with no result. If I manually add this dependency it complains on another thing and so on which makes me think it is something else that causes this.
Anyone have any clue? here is my pom.xml as well

You have a bad dependency.

Whenever you encounter "Also this project have been working but now it wont start it anymore." you need to figure out what was changed when the project broke. In order to do so, you need source control (like git, mercurial or bazaar). Check out commits until you find the one where it worked before the commit and not after. Then look into what was changed.
If you use git, then git bisect may be helpful. See https://git-scm.com/book/en/v2/Git-Tools-Debugging-with-Git#_binary_search for how to do this.
If you don't use source control, now is a good time to reconsider.

How to import artifact from one subproject into another in multimodule project?

Collegues, i have subproject utils in my multimodule project. The pom looks like:
<?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"

</configuration>
</plugin>
</plugins>
</build>
</project>
I run command mvn clean install and utils-1.0-SNAPSHOT.jar is created in the local maven repository.
After that i add next dependency into pom of another subproject
<dependency>
<groupId>com.comp.kort</groupId>
<artifactId>utils</artifactId>
<version>1.0-SNAPSHOT</version>
<scope>provided</scope>
</dependency>
But when i add import com.comp.kort to classes of my second subproject i receive Can't resolve symbol 'kort'.
What should i to import com.comp.kort in the second subproject correctly?
mvn dependency:tree on my second subproject shows:

It seems <scope>provided</scope> is not right, and you can remove it.
Provided is much like compile, but indicates you expect the JDK or a container to provide the dependency at runtime. For example, when building a web application for the Java Enterprise Edition, you would set the dependency on the Servlet API and related Java EE APIs to scope provided because the web container provides those classes. This scope is only available on the compilation and test classpath, and is not transitive.
You can see here

Maven package error: An attached artifact must have a different ID than its corresponding main artifact

As Dimitri suggested, I solved this by adding classifier to spring-boot-maven-plugin:
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<configuration>
<classifier>boot</classifier>
</configuration>
</plugin>

Looks like a bug in spring-boot-maven-plugin together with your version of Maven.
As far as I can tell, Maven knows that the WAR plugin will generate the file target/compiled-1.0-SNAPSHOT.war. when it asks the spring-boot-maven-plugin for its output, it will get the same name. Since Maven doesn't know what the plugin does, it will assume that both are configured to create the same output file and stop since that can't be what you want (the files will overwrite each other).
Try with the latest version of Maven or file a bug against the spring-boot-maven-plugin. Let them know which version of Maven you're using.

I am currently facing the same issue.
However, providing the required parameter finalName, I can see that the .war file is well boot-ified.
Please note that I still encounter the error message in both cases (with and without the finalName).
Here is the link to the issue I opened on the Spring Boot project: https://github.com/spring-projects/spring-boot/issues/2060

All that is required is to include a <finalName> tag in the build section.
<build>
<finalName>myJar</finalName>
</build>
