Spring boot application crashing on starting:Togglz: java.lang.IllegalStateException: Could not find the FeatureManager - spring

i'm using toggle feature with toggle dependencies but when i tried to bring up the services some times application startup is failing saying could not find FeatureManger.
I followed server approaches but none of them worked well. in this post the issue been highlited by updating jar dependecy, even that also not working.
Please suggest if you have other fix available for this issue.

Can't get Netbeans Project to acknowledge existing Tomcat or Glassfish Server

I haven't been able to figure out what I'm missing here.
I've installed Tomcat and can spin it up fine. (Glassfish too, in my efforts, but I had removed it when I took the screenshot.)
So now I want to hook my project up to the Tomcat instance so I can have Netbeans deploy it for me automatically.
I right-click on my project, go down to Properties. In Project Properties I select 'Run' and go to the drop down to select my server. Only, there's no servers.
Why is it not showing up here? Am I going about this all wrong?
Thanks in advance for any help!
Other potentially useful notes:
* Using Gradle (for my first time)
* Using Spring Boot (for my first time)
* On Windows 10 (don't hate me, I don't love it either)
I was chasing the wrong problem. Spring-boot provides an embedded server so I had no need to install and provide my own.
My real problem was that I had dependencies declared for jpa, postgresql, etc. that I hadn't configured in application.properties. When I tried to run, I'd get an error saying "a problem occurred starting process /path/to/my/jdk/java.exe". I couldn't figure what was going on and, looking around, I saw the issue mentioned in my question about the server.
The solution was to simply comment out the dependencies in my build.gradle until I was ready for them. After I got my PostgreSQL DB set up and added the configureation to application.properties, I was able to un-comment them and it's working great.

Intellij Hot Reload doesn't work properly after reload it is unable to find the spring injected bean

I am working with a spring boot project in intelliJ and seems like hot reloading is not working as expected. I have configured the project and IDE so that hot reload should work i.e i have checked build project automatically under settings also in registry i have checked compiler.automake.allow.when.app.runing and have added spring boot dev-tools dependency and with these steps intelliJ does hot reload when i change my source code, But i don't see much difference in productivity by saying, that I mean a simple restart server and hot reload is almost working same, also many of the times when hot reload takes place i get bean dependency resolve error
`Field courseRepository in com.practice.jpamappings.JpaMappingsApplication required a bean of type 'com.practice.jpamappings.repositories.CourseRepository' that could not be found`.
I have checked with the error and it's not related to the missing bean cause when i restart the server everything works fine so does hot reload have to do something with this missing bean error ?
did i configure the hot reload properly ? or i need to do some more efforts to make it work properly.

Spring Boot Run Configuration Issues

I am trying to run my spring boot application (via Run As -> Spring Boot Application) in a tomcat8 container on STS and I am receiving these errors:
Caused by: java.lang.IllegalStateException: Expected method not found: java.lang.NoSuchMethodException: org.springframework.boot.context.embedded.tomcat.TomcatEmbeddedContext.addApplicationListener(org.apache.catalina.deploy.ApplicationListener)

I have searched around for this quite a bit and have found little to guide me in figuring out what the problem is. After going through the spring boot code in the debugger I see that the object named "instance" referenced in the TomcatWebSocketContainerCustomizer.addListener() uses reflection to retrieve a handle to it. This object is associated with the tomcat 7.0.53 jar ($HOME/.m2/repository/org/apache/tomcat/tomcat-catalina/7.0.53/tomcat-catalina-7.0.53.jar). I do not see this in any of my maven dependencies and have tried several techniques to force it to tomcat 8.0.20, nothing seems to work.
After banging my head for a while I started looking at the run configuration for the project in STS (via Run As -> Run Configurations). I found that the Source tab shows tomcat 7.0.53 above version 8.0.20 along with several dependencies that aren't referenced in maven. I am at a loss on where these values come from and not sure how to edit it. For some reason when I try to manually delete these legacy jar files STS doesn't allow me to delete any of them.
Does anyone have an idea of where these dependencies may be coming from and how I can remove them?
They do reference my $HOME/.m2/path/to/tomcat-catalina/<version> dir, so I could simply remove them from my .m2 and theoretically it may work but I'd rather not do this if I don't have to.
I am using spring boot 1.2.x and all of them have this problem.
thanks.
I've got two ideas that you might try.
1) It is possible, that this may be manifestation of this bug in STS 3.6.4: https://issuetracker.springsource.com/browse/STS-4085
The depencies you aren't expecting to see may be coming from the maven 'test' scope. (The bug explicitly mentions 'srt/test' but the same happens with jar dependencies). You can verify whether this bug is the cause by using the regular "Run As Java Application" on your main class.
If that works, then it is almost certainly this bug. If it also fails with a similar error then its something else... then try:
2) You must be getting the unwanted tomcat version from somewhere, probably indirectly as dependency of something else.
Try using the m2e 'dependency hierarchy' to find where it came from like so:
open pom.xml
Click the 'Dependency Hierarchy' tab.
Type 'tomcat' in the 'Filter' box.
I finally figured it out.
In my $WORKSPACE/.metadata/.plugins/org.eclipse.m2e.core/workspacestate.properties it lists all poms, jars and wars from my workspace build with the maven plugin. I noticed that a pom in the file points to the exact version tomcat that is being loaded in my spring boot project. Once I deleted these projects from my STS I can successfully launch the spring boot app :-)
When I re-import the maven projects back to STS the error occurs again, then disappears when I remove them.
These projects have no connection to the project that I am trying to launch. Therefore I think the bug is in m2e.
I'll file a bug and update this post when it is complete.
thanks #Kris for working through it with me.

Spring Boot v1.2 AbstractMethodError due to RepositoryInformation

Im building an application based on Spring Boot v1.2. While my application boots successfully and executes well (so far.. ), I'm unable to test using the spring boot framework because of an AbstractMethodError.
The last few lines of the trace are as below

To analyze the above error, I checked the jar files from classpath involving the above classes. So the info is available as below
jar:file:/C:/rearch/intellij-workspace/springbootproj/lib/spring-aop-4.1.2.RELEASE.jar!/org/springframework/aop/framework/ProxyFactory.class
jar:file:/C:/rearch/mavenrepo/org/springframework/data/spring-data-commons/1.9.1.RELEASE/spring-data-commons-1.9.1.RELEASE.jar!/org/springframework/data/repository/core/RepositoryInformation.class
jar:file:/C:/rearch/intellij-workspace/springbootproj/lib/spring-data-jpa-1.3.3.jar!/org/springframework/data/jpa/repository/support/LockModeRepositoryPostProcessor.class
jar:file:/C:/rearch/intellij-workspace/springbootproj/lib/spring-test-4.1.2.RELEASE.jar!/org/springframework/test/context/support/DependencyInjectionTestExecutionListener.class
I'm not exactly sure on why spring-data-commons is coming up from maven repostory folder, while the others are being served from the project library.
While I debug that, I meanwhile need your help in figuring out the version compatibility between the above libraries.
I wasnt able to exactly pin point on what exactly is causing the error. Please help!
Thanks
The issue was with the intellij configuration of libraries which conflicts with Spring boot application. I manually replaced the required libraries from Maven repository and that worked out for me.
Per request from Elron..
Open the project folder in explorer and verify if the third party library versions in your project matches the ones you actually expect it to be. If something doesnt match, just replace the file with the one you expect it to be. In my case, since I use Maven, I didnt see a need for explicitly saving those libraries in a new lib folder under the project. So, I just deleted all of the files inside the lib folder and things started working again.
For fix this error, change the spring-data-jpa version to 1.5.0.RELEASE
I have faced this issue .
Get rid of spring-data-commons and change spring-data-jpa version to 1.9.0.RELEASE.

Struts2 Dispatcher initialization failure with maven - jetty

I have the following problem:
I am working on a Web-Project using Struts2 with Tiles supported by a combination of Hibernate and Spring. In addition I am using Maven (which I'm new to) and the jetty server container. So my coworker told me what to do: just check out the project from the svn-repository and run the command (sudo) mvn jetty:run. According to my coworker this should work just fine, as it does when he checks out the project. But I always get the same error:
2011-08-22 10:09:20,568 ERROR org.apache.struts2.dispatcher.Dispatcher.error:38 -
Dispatcher initialization failed
Unable to load configuration. - [unknown location]
I already tried to re-check out the project, cleaned and updated maven, but still, the same error.
I think it has something to do with a missing struts2 .jar-file, but I thought maven downloads all necessary libraries automatically. Please give me a hint what could be missing, I'm sure it's something simple I overlooked.
Thanks in advance.
