Generated application won't start with `springBootVersion-3.1.3`; throws java.lang.NoClassDefFoundError: org/springframework/boot/SpringApplication

[anothergoodguy]

Overview of the issue

Hi I have used the attached .yo.rc.json to generate a sample app to validate 3.1.3 introduction. after building the application with ./gradlew clean -Pdev bootJar the application wont start with java -jar build/libs/sample-rest-0.0.1-SNAPSHOT.jar Here is the error I get:

##### **Motivation for or Use Case**

Application won't start

##### **Reproduce the error**

basic generation flow and used the attached jdl for sample entities

##### **Related issues**

not aware of any

##### **Suggest a Fix**

Will add as comments if i find any...

##### **JHipster Version(s)**

latest commits of the  branch `main` and commit  `6db9e9e8`.
I suspect, this is something to do with Spring-boot-`3.1.3`, if I change the version to `3.1.2` it works fine...

[qmonmert]

@anothergoodguy I think you must use prod profile: ./gradlew clean -Pprod bootJar

[anothergoodguy]

@qmonmert we have dev, stage and prod environments. I usually duplicate dev for stage and make the needed env changes. thanks for the quick resolution. will try to test later tonight and will share you the observations, if any.

[anothergoodguy]

here are some observations:

1. build with ./gradlew clean -Pprod bootJar
2. run with java -jar build/libs/sample-rest-0.0.1-SNAPSHOT.jar
3. observe that it's using Spring Boot 3.1.2 instead of 3.1.3, even though the gradle properties has the correct entry

# Dependency versions
jhipsterDependenciesVersion=8.0.0-SNAPSHOT
# The spring-boot version should match the one managed by
# https://mvnrepository.com/artifact/tech.jhipster/jhipster-dependencies/8.0.0-SNAPSHOT
springBootVersion=3.1.3
# The hibernate version should match the one managed by
# https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-dependencies/3.1.3 -->
hibernateVersion=6.2.7.Final
mapstructVersion=1.5.5.Final
archunitJunit5Version=1.1.0

and the result:

java -jar build/libs/sample-rest-0.0.1-SNAPSHOT.jar

@anothergoodguy Did you build locally jhipster bom and generator projects?

[anothergoodguy]

no @DanielFran I dont have the bom project locally, I have generator locally and am using the generator by building the docker image locally.

[DanielFran]

@anothergoodguy Can you confirm this is still happening? @qmonmert confirmed that with current main branch this does not happen now...

[qmonmert]

@DanielFran I confirm, but this is strange

[anothergoodguy]

hey @DanielFran, I have the commit 15970f6164. and this is still happening with gradle, but I tried out of curiosity with maven as well, interestingly it's working fine with maven. See the results below:

opps looks like I overlooked that the app didn't start in maven either but looks like a different issue, sharing it here thinking these might be classpath corrections:

Error starting ApplicationContext. To display the condition evaluation report re-run your application with 'debug' enabled.
2023-09-01T22:27:50.714+05:30 ERROR 11977 --- [           main] o.s.b.d.LoggingFailureAnalysisReporter   :

***************************
APPLICATION FAILED TO START
***************************

Description:

An attempt was made to call a method that does not exist. The attempt was made from the following location:

    co.elastic.clients.transport.endpoints.SimpleEndpoint.pathEncode(SimpleEndpoint.java:99)

The following method did not exist:

    'java.lang.String org.apache.http.client.utils.URLEncodedUtils.formatSegments(java.lang.String[])'

The calling method's class, co.elastic.clients.transport.endpoints.SimpleEndpoint, was loaded from the following location:

    jar:file:/Users/thatguy/jhipster/biskate/store-trial/target/store-0.0.1-SNAPSHOT.jar!/BOOT-INF/lib/elasticsearch-java-8.7.1.jar!/co/elastic/clients/transport/endpoints/SimpleEndpoint.class

The called method's class, org.apache.http.client.utils.URLEncodedUtils, is available from the following locations:

    jar:file:/Users/thatguy/jhipster/biskate/store-trial/target/store-0.0.1-SNAPSHOT.jar!/BOOT-INF/lib/httpclient-4.5.3.jar!/org/apache/http/client/utils/URLEncodedUtils.class

The called method's class hierarchy was loaded from the following locations:

    org.apache.http.client.utils.URLEncodedUtils: jar:file:/Users/thatguy/jhipster/biskate/store-trial/target/store-0.0.1-SNAPSHOT.jar!/BOOT-INF/lib/httpclient-4.5.3.jar!/

Action:

Correct the classpath of your application so that it contains compatible versions of the classes co.elastic.clients.transport.endpoints.SimpleEndpoint and org.apache.http.client.utils.URLEncodedUtils

[mshima]

Both errors are related to version conflicts. Which may be fixed (or caused) by transitive dependencies. jhipster main is a moving target, so is jhipster-bom main. It’s not possible to use a jhipster git commit without the matching jhipster-bom commit.

If it’s not reproducible in main using a current jhipster-bom snapshot we should close the issue.

[anothergoodguy]

I tested it on a setup with both bom and geneator latest commits and this issue is no longer present with gradle; but I see the above mentioned classpath issue in maven still. you may take a call to close the ticket as per the program guidelines. However there is some other classpath/aceess-restrictions issue I see on both main branch and 8.0.0-beta.2; and I will file a separate issue ticket for it.

[mshima]

@anothergoodguy the original issue is not reproducible anymore. If you the elasticseach bug persists please open a new issue.
