I am currently playing with some proof-of-concept work in Spring Boot and GCP data storage.
My pom.xml
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
<version>2.4.0</version>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-gcp-data-datastore</artifactId>
<version>1.2.6.RELEASE</version>
</dependency>
Issue: Spring Boot fails to start
When I attempt to launch the application, I get:
Exception in thread "main" java.lang.NoClassDefFoundError: org/springframework/core/metrics/ApplicationStartup
at org.springframework.boot.SpringApplication.<init>(SpringApplication.java:251)
at org.springframework.boot.SpringApplication.<init>(SpringApplication.java:264)
at org.springframework.boot.SpringApplication.run(SpringApplication.java:1309)
at org.springframework.boot.SpringApplication.run(SpringApplication.java:1298)
What I tried
I tried adding the Actuator dependency.
But that did not do the trick.
I cannot figure out what dependency I am missing. I see the class definition here in 5.3.0-M2 documentation, but I'm not sure what dependency it exists in.
I also tried adding following metrics dependencies:
spring-cloud-gcp-starter-metrics
spring-metrics
spring-cloud-stream-metrics
I searched in findjar.com with no luck.
I wouldn't mind disabling it as well if that is possible.
Update:
I added:
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-core</artifactId>
<version>5.3.1</version>
</dependency>
Which gives me a new error:
An attempt was made to call a method that does not exist. The attempt
was made from the following location:
org.springframework.boot.SpringApplication.run(SpringApplication.java:324)
The following method did not exist:
'void org.springframework.context.ConfigurableApplicationContext.setApplicationStartup(org.springframework.core.metrics.ApplicationStartup)'
The method's class,
org.springframework.context.ConfigurableApplicationContext, is
available from the following locations:
...
Action:
Correct the classpath of your application so that it contains a
single, compatible version of
org.springframework.context.ConfigurableApplicationContext
I was able to solve this by downgrading Spring Boot:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
<version>2.3.3.RELEASE</version>
</dependency>
Guess it's just not compatible with 2.4.0 yet.
Specifically I also had to ensure that I used 2.3.3.RELEASE and not anything more recent due to other issues I ran across.
I don't have the spring-cloud dependency, but when upgrading to Spring Boot 2.4 from 2.3 I got the same error.
Exception in thread "main" java.lang.NoClassDefFoundError:
org/springframework/core/metrics/ApplicationStartup
Per conversation in this thread (https://github.com/spring-projects/spring-boot/issues/24880) I upgraded to Spring Framework 5.3.3 and it fixed the problem.
I had the same issue caused by an old version of spring-context JAR file loaded instead of the appropriate version.
Ensure that there were no reminiscence of old libraries in your classpath.
I had a similar issue, and it was resolved by adding the following maven dependency:
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context-support</artifactId>
<version>5.3.8</version>
</dependency>
I was having the same issue but with:
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-test</artifactId>
<version>5.2.9.RELEASE</version>
<scope>test</scope>
</dependency>
And the error disappeared after I upgraded to:
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-test</artifactId>
<version>5.3.3</version>
<scope>test</scope>
</dependency>
May this help, upgrade spring-cloud to the latest version.
This works for me when I faced your first error :
Exception in thread "main" java.lang.NoClassDefFoundError: org/springframework/core/metrics/ApplicationStartup
See the twitter thread here, thanks to Stéphane and Arnaud for the help.
I had the same problem, but that was caused by spring-security-ldap that i also import in version 5.4.x
Upgrade spring-security-ldap to version 5.5.0 solved the problem for me.
I had this issue when adding a Spring Boot test to a library for the first time. In my case, the library did not have a Spring Boot application.
This did the trick:
#SpringBootApplication
public class TestApplication {
public static void main(final String[] args) {
SpringApplication.run(TestApplication.class, args);
}
}
Using only spring-boot-starter-test as a Spring dependency.
Check if another dependency doesn't have dependency to spring-core with older version
May this will help someone, who is facing this error.
=> Error should look like this:
Exception in thread "main" java.lang.NoClassDefFoundError: org/springframework/core/metrics/ApplicationStartup
at org.springframework.context.support.AbstractApplicationContext.<init>(AbstractApplicationContext.java:229)
at org.springframework.context.support.GenericApplicationContext.<init>(GenericApplicationContext.java:112)
at org.springframework.context.annotation.AnnotationConfigApplicationContext.<init>(AnnotationConfigApplicationContext.java:67)
at org.springframework.context.annotation.AnnotationConfigApplicationContext.<init>(AnnotationConfigApplicationContext.java:91)
Solution to the Problem:-
Go to Project folder\ Right click\ Maven\ Update maven project.
Check your Spring version (pom.xml-> view the properties).
Change the Spring version to an older/new version..Otherwise use this
<properties>
<maven.compiler.target>1.8</maven.compiler.target>
<maven.compiler.source>1.8</maven.compiler.source>
<spring.version>5.2.0.RELEASE</spring.version> <!--add this version-->
</properties>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-core</artifactId>
<version>${spring.version}</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-beans</artifactId>
<version>${spring.version}</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context</artifactId>
<version>${spring.version}</version>
</dependency>
</dependencies>
<dependency>
<groupId>org.springframework</groupId> <!-- sql dependency for jdbc-->
<artifactId>spring-jdbc</artifactId>
<version>${spring.version}</version>
</dependency>
After adding above things, Save it(Please wait for the code to build..).

I had the same Spring Boot ClassNotFoundException ApplicationStartup issue, the solution was for me to ensure that the spring boot version in my gradle plugin is the same than the dependencies in my build.gradle.kts like:
plugins {
id("org.springframework.boot") version "2.5.3"
...
}
dependencies {
implementation("org.springframework.boot:spring-boot:2.5.3")
...
}
How to get the list of all dependencies with versiosn used in spring-context 4.3.6 Release ? I do see that for spring boot in spring.io page but not for spring-context
If you are using maven adding this will resolve all dependencies
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context</artifactId>
<version>4.3.6.RELEASE</version>
</dependency>
It has following dependencies:
org.springframework:spring-context:4.3.6.RELEASE
org.springframework:spring-aop:4.3.6.RELEASE
org.springframework:spring-beans:4.3.6.RELEASE
org.springframework:spring-core:4.3.6.RELEASE
commons-logging:commons-logging:1.2
org.springframework:spring-expression:4.3.6.RELEASE
Wanted to make use of openejb on top of tomcat v7 using maven instead of installing tomee. Referring to Apache documentation, 3 dependencies have to be added to the maven project.
<dependency>
<groupId>org.apache.openejb</groupId>
<artifactId>javaee-api</artifactId>
<version>6.0-6</version>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>org.apache.openejb</groupId>
<artifactId>openejb-core</artifactId>
<version>4.7.4</version>
</dependency>
<dependency>
<groupId>org.apache.openejb</groupId>
<artifactId>tomee</artifactId>
<version>1.7.4</version>
</dependency>
but the last depency generates following error: Missing artifact org.apache.openejb:tomee:jar:1.7.4
The correct artifactId being visible in:
http://mvnrepository.com/artifact/org.apache.openejb/apache-tomee/1.7.4
is apache-tomee and not tomee
so, replace the last depency by the following one and the problem will be solved:
<dependency>
<groupId>org.apache.openejb</groupId>
<artifactId>apache-tomee</artifactId>
<version>1.7.4</version>
</dependency>
I am trying to download the org.springframework.web.servlet using maven dependency
but maven could not download it.i want to know is this dependency is there in maven or not
<dependency>
<groupId>org.springframework</groupId>
<artifactId>org.springframework.web.servlet</artifactId>
<version>3.1.1.RELEASE</version>
</dependency>
or spring has changed its dependency or can we use some alternate dependency for it.please suggest
The package org.springframework.web.servlet is contained in the spring-webmvc module. Use this dependency:
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
<version>3.1.1.RELEASE</version>
</dependency>`
Update: Since this post is quite old, please check for newer versions of the spring framework. Release 3.1.1.RELEASE is quite out-dated.
When I upgrade to activemq-all-5.6.0
I get this error during server startup
SLF4J: Class path contains multiple SLF4J bindings
I don't have this issue when using activemq-all-5.5.1
On checking I do find that there StaticLoggerBinder.class in both activemq-all-5.6.0.jar and slf4j-log4j12-1.5.10.jar which is causing the issue
Please do help in debugging this issue
My pom.xml is as follows
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-api</artifactId>
<version>1.5.10</version>
</dependency>
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>jcl-over-slf4j</artifactId>
<version>1.5.10</version>
<scope>runtime</scope>
</dependency>
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-log4j12</artifactId>
<version>1.5.10</version>
<scope>runtime</scope>
</dependency>
The active mq dependency is like this
Old Version 5.5.1 (This works)
<dependency>
<groupId>org.apache.activemq</groupId>
<artifactId>activemq-all</artifactId>
<version>5.5.1</version>
</dependency>
New Version 5.6.0 (This gives the error)
<dependency>
<groupId>org.apache.activemq</groupId>
<artifactId>activemq-all</artifactId>
<version>5.6.0</version>
</dependency>
Thanks in advance.
The ActiveMQ guys use the Maven Shade Plugin to create the activemq-all "ueber" jar. Somewhere between version 5.5.1 and 5.6.0 they added the org.slf4j:slf4j-log4j12 dependency - hence your problem.
Unfortunately because they used the shade plugin you can not use exclusions in your activemq-all dependency definition in your POM.
Instead you will need to completely replace the activemq-all dependency with all the required individual dependencies (except of course the org.sl4j-log4j12 one).
The following page details all the required dependencies:
http://activemq.apache.org/initial-configuration.html#InitialConfiguration-RequiredJARs
Alternatively the following is the list of all dependencies (required and optional) included in the activemq-all jar (taken from the configuration of the shade plugin in the activemq-all pom):
org.apache.activemq:activemq-camel
org.apache.activemq:activemq-core
org.apache.activemq:activemq-console
org.apache.activemq:activemq-jaas
org.apache.activemq:activemq-optional
org.apache.activemq:kahadb
org.apache.geronimo.specs:geronimo-jms_1.1_spec
org.apache.geronimo.specs:geronimo-jta_1.0.1B_spec
org.apache.geronimo.specs:geronimo-j2ee-management_1.1_spec
org.apache.geronimo.specs:geronimo-annotation_1.0_spec
org.slf4j:slf4j-api
org.slf4j:slf4j-log4j12
log4j:log4j
Hope that helps.
I had the same problem while using Spring. What helped me was replacing the dependency of activemq-all with:
<dependency>
<groupId>org.apache.activemq</groupId>
<artifactId>activemq-spring</artifactId>
<version>5.14.3</version>
</dependency>
Hope this will help anyone...
