I have created a Spring Starter data jpa project and its connecting with mysql. through STS its running fine.
i wanted to deploy it individually so i clean install the application using maven and used java jar <jarfile.jar> in command prompt.
I followed the video of java brains.
Below is the error which get
JAXB is not found.
It seems that you set the scope of the JAXB dependency to provided or built the project for an old Java Version (like Java 8) that comes with JAXB and run it with a newer Java version (like Java 10) that does not come with JAXB.
You can fix this by adding the JAXB dependency to the classpath when running the JAR or by adding the dependency to your project manually(or set the scope to compile)

I've got a Spring Boot Maven project that creates an executable fat .war. I can run this .war using java -jar without any issues as all dependencies are located within the far .war.
However, I can't run the project with the Spring Boot Devtools using mvn spring-boot:run as it fails to find some dependencies at runtime and throws unhandled exceptions.
For example, we've got an indirect dependency on jaxb-runtime-2.3.1.jar which in turn has a dependency on jaxb-api.2.3.1.jar. Both .jars are present in the fat .war but if I run the project with mvn spring-boot:run it can find jaxb-runtime ok but fails to find jaxb-api with the message:
java.nio.file.NoSuchFileException: ~/.m2/repository/org/glassfish/jaxb/jaxb-runtime/2.3.1/jaxb-api-2.3.1.jar
Note, jaxb-api-2.3.1.jar is present in the maven cache at:
~/.m2/repository/javax/xml/bind/jaxb-api/2.3.1/jaxb-api-2.3.1.jar
however it seems to be looking for it in the same location as the parent jaxb-runtime-2.3.1.jar which is located at:
~/.m2/repository/org/glassfish/jaxb/jaxb-runtime/2.3.1/
There's a long list of similar exceptions that follow this pattern. It's quite a large project but here are some of the versions we're using:
Spring Boot: 2.1.9.RELEASE
spring-boot-maven-plugin: 2.1.9.RELEASE
maven-compiler-plugin: 3.8.1
spring-boot-devtools: not specified in pom
Why does spring-boot:run not locate dependencies in the same way as the maven build? How can I instruct it where to find these dependencies?
I am developing an application for MULE ESB CommunityEdition (3.8.1 version).
I have included (provided by MULE) SPRING 4.1.6.RELEASE in project.
For persistence layer I set up Hibernate 4.3.11.FINAL.
My code is based on this idea (https://www.ricston.com/blog/jpa-mule/).
So basically i have included in the project (besides MULE dependencies):
hibernate-entitymanager (4.3.11.Final)
hibernate-core (4.3.11.Final)
hibernate-jpa-2.1-api (1.0.0.Final)
spring-orm (4.1.6.RELEASE)
And everything was working perfectly fine until i started to use Java 8 API...
Whatever I do: any lambda, stream or anything I am still getting error:
org.hibernate.jpa.boot.archive.spi.ArchiveException: Could not build ClassFile
What I did until now:
tried to add org.javassist dependency (in version from 3.18.0-GA to 3-22.0-GA) - nothing happened,
tried to exclude org.reflections.0.9.9 dependency (mule is including that in some its core dependencies): also nothing happened
I spent on this about 5 hours I am really close to give it up... I really need hibernate cause this project will include many db operations
What else Can i Try to do?
Problem solved!!
I was using mvn dependency:tree to check if there are any org.javassist dependencies in project.
And there weren't...
Then I checked the folder: {mule_home}/lib/opt and there was an old version of org.javassist library!
So: I downloaded latest org.javassist jar and I put it in the {mule_home}/lib/user folder.
Now it works like a charm :)
Please check if your Anypoint Studio is pointing correct JDK.
Check below
Preference> Installed JRE >> It should have JDK 1.8 checked.
I am using STS 3.6.1, Java 7, Grails 2.4.3.
When create a normal Grails project, it works good. However, my Grails project need to depends on other java projects, so I convert it to maven project. After that STS prompt error
Could not find the grails dependency file. This probably means that there is a bad dependency in the pom file.
java.lang.Exception
The maven grails project can be build in grails command.
How to resolve is issue? Or if there is walk around to let grails project depends on other Java project.
I'm trying to build a complete Spring Framework distribution for version 3.2.4.RELEASE without using maven (just the spring jars) and managed to manually get all jars except for spring-asm.
Spring-asm stops at version 3.1.4. Why is that?
I have older spring distributions up to 3.1.1 (those for which you had a zip file, not forced to use maven) and all have the same spring-asm jar inside, with the same version.
Why is there no spring-asm-3.2.4.RELEASE jar?
Here is from release notes for 3.2
we've eliminated the dedicated spring-asm jar in M2 in favor of including org.springframework.asm classes directly in spring-core
I have Dynamic Web Application project in eclipse that was converted to maven project.
Problem is that all dependencies are copied to:
<project>/target/<project>-SNAPSHOT/WEB-INF/lib
not <project>/WebContent/WEB-INF/lib
so when I run application from eclipse, there are no libs from maven and I get some errors.
I assume that application started from eclipse i.e on tomcat server gets it source from <project>/WebContent/WEB-INF/lib.
You should use m2e (Maven Plugin for Eclipse). It automatically adds Maven dependencies to the classpath, so you don´t need them in /WEB-INF/lib while running from Eclipse.
