Error in Eclipse Luna: java.lang.NoClassDefFoundError: org/eclipse/osgi/baseadaptor/HookConfigurator - osgi

I write project work with osgi + aspectj. It work ok in Eclipse Kepler, but when I upgrade to eclipse 4.4 (Luna) then get error:
I open org.eclipse.osgi*.jar found in Eclipse Kepler and see class org.eclipse.osgi.baseadaptor.HookConfigurator
But in Luna not found.

I have followed the instructions here, it's based on Eclipse Kepler, but I use Eclipse Luna.
Please help me.

Equinox Luna has change many of the internal details that require all equinox framework hook implementations to be migrated to use the new hooks. It is unclear to me what you have installed that is trying to implement HookConfigurator from the stacktrace. If it is the Equinox weaving support which supports weaving with aspectj then you will need the Equinox weaving bundles released with the Equinox 4.4 (luna) release as well.
If not then what ever framework extension you have installed that does weaving will need to be migrated to the new Equinox framework specific hooks in luna.

Spring Boot and Vaadin - ClassNotFoundException: org.springframework.web.context.support.WebApplicationObjectSupport

I have generated Spring Boot Vaadin project at start.spring.io with just the Vaadin dependency (Maven project, Spring Boot 1.5.1, Vaadin dependency).
I have unzipped the dowloaded .zip file and imported the project to STS (File -> Import -> Existing Maven Projects). I tried to run the application but I got this exception:

The project can be build by Maven (clean install) when skipping tests. With tests enabled it fails with the same error.
I have already tried:
to import project and run it in different IDEs (STS, Eclipse, Idea)
run the application as Spring Boot App, Java Application, from test class
other versions of Spring Boot (1.5.1, 1.4.4)
different Java 8 (jdk1.8.0_65, jdk1.8.0_121)
restart IDE
Based on the comment from p.streef I found the solution. I cleared Maven repository (more precisely I deleted content of .m2\repository\org\springframework folder where Spring .jar files are located) and run the application again. Then it worked.
Edit
It seems like frequent problem. Recently I tried to create a new Spring Boot project with Vaadin, JPA and H2 dependencies. At first I got:
spring boot Error creating bean with name 'entityManagerFactory'
I deleted jars in .m2\repository\org\hibernate and run mvn clean install and got:
spring boot NoClassDefFoundError: javassist/bytecode/ClassFile
I deleted jars in .m2\repository\org\javassist and run mvn clean install
Now it worked. So when you get some error running newly created Spring Boot project saying that some class is missing, clean jars in your Maven repository and try it again.

After this error, the deploy go fine.
But if I modify a static file (jsp for example) jrebel works fine...if I modify a java class, jrebel not works.
I don't know if is a problem relative to the error shown in console at deploy time.
In the past I userd Jrebel with eclipse with servlet (not spring) and it worked fine.
I use:
- IntellijIDEA 2016.1.1
- Java 1.8
- Spring 4.2.5
Can you help me???
Thanks
What version of tomcat are you using? 9.0.0 milestone? Grab JRebel 6.4.2 release from here and install the zip using the same instructions as for installing the nightly build at here, should fix the error.

Trouble setting Classpath for Cpsuite with Maven

Using Maven I am creating a jar-with-dependencies for a project that uses ClasspathSuite to create a JUnit test suite. When running the jar from the command line I am running into an issue where the project classpath isn't being supplied like it would be in Eclipse.

I need the project classpath so that ClasspathSuite can scan my files to build a junit class suite. I have been searching a number of ways to allow maven to include the classpath in my pom such as <additionalClasspathElements> or <Class-Path> but I cannot get the value to appear in the system property java.class.path. At this point I am unsure if I am just walking down a rabbit hole that isn't going to work.
Is it possible to have a classpath in my jar's manifest that will point to one of the jar's directory? In this case ./com/....
How can I have this classpath referenced so that maven will include it when the jar is executed?

Failure running JavaFX 2.2 using Maven

I use Zen's Maven plugin to develop my JavaFX 2.2 application using Maven. The following is the plug-in declaration.
<plugin>
<groupId>com.zenjava</groupId>
<artifactId>javafx-maven-plugin</artifactId>
<version>2.0</version>
<configuration>
<mainClass>${mainClass}</mainClass>
</configuration>
</plugin>
I fixed the classpath using the following command:
mvn com.zenjava:javafx-maven-plugin:2.0:fix-classpath
and the fixing probably succeeded.
The compilation also worked but the process did not generate JavaFX main files such as the following:
/com/javafx/main/Main$1.class
/com/javafx/main/Main$2.class
/com/javafx/main/Main.class
/com/javafx/main/NoJavaFXFallback.class

What is going wrong and how can I fix it?
The main jar doesn't contain these classes, but the plugin generates an additional jar in the "target/jfx" directory (or something like this). Use that jar to start your application.
