Summary: I have a very basic Java 1.8 and Spring 4.0.5 project, I'm using Maven 3.2.3 to manage it. Maven exec cannot seem to see my Spring context, even though it appears to me that it is in the classpath.
My spring context is in
<project root>/src/main/resources/spring/ch2-beans.xml
and I load it using:
ClassPathXmlApplicationContext applicationContext = new ClassPathXmlApplicationContext("/spring/ch2-beans.xml");
after a "mvn clean compile" I see
<project root>/target/classes/spring/ch2-beans.xml
and when I run:
mvn -X exec:java -Dexec.mainClass="com.wiley.beginning.spring.ch2.Main"
I see the following debug output which makes me think the classpath is indeed correct:
[DEBUG] Collected project classpath [/Users/me/Documents/workspace/BeginningSpring/chapter2/spring-book-ch2/target/classes]
[DEBUG] Adding to classpath : file:/Users/me/Documents/workspace/BeginningSpring/chapter2/spring-book-ch2/target/classes/
Yet I get the following error:
Caused by: org.springframework.beans.factory.BeanDefinitionStoreException: IOException parsing XML document from class path resource [spring/ch2-beans.xml]; nested exception is java.io.FileNotFoundException: class path resource [spring/ch2-beans.xml] cannot be opened because it does not exist
Can anyone point me in the direction of sorting this out? What I've posted above is the result of many different attempts to solve this, and I'm stumped by the error when it certainly appears that the file path should be in the classpath, so perhaps this is something that has changed since I last coded (a while ago..). Thanks!
Update..
Thinking that it might be some classpath issue with exec:java I ran the same code inside a unit test, executed within maven. Same error. I've also tried loading the xml file as "classpath:/spring/ch2-beans.xml", did not fix it.
There was a hyphen in the file name of the Spring configuration I was trying to load, and it appears that the classloader won't accept that. Hyphens are illegal in identifier names in Java, apparently this applies also to external resources.
Once I removed the hyphen from the xml file name, it was found.
On a related note, I'm pretty annoyed with the "Beginning Spring" book example which uses these hyphenated names.

I just started right now a new project in Intellij using Spring Boot ver 2.1.3 and Flyway 5.2.4 with Java 11.
After try to start my project i got :
Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'flyway' defined in class path resource [org/springframework/boot/autoconfigure/flyway/FlywayAutoConfiguration$FlywayConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.flywaydb.core.Flyway]: Factory method 'flyway' threw exception; nested exception is java.lang.IllegalStateException: Cannot find migrations location in: [classpath:db/migration] (please add migrations or check your Flyway configuration)
I have the following folders:
As you can see i have "db/migration" but without any migration, i just started right now. Debugging the class FlywayAutoConfiguration i got the following:
So, i tried to return all files in "classpath:", see:
Note that i just have "application.properties" file.
It is not that much useful or accurate answer.
But This issue make you frustrated so that i give this solution.
Note: Strange but it's true, Sometime it's not allow copy paste because your folder created db.migration and it expact db->migration(It's not same in this scenario). So whenever you start from scratch. Go to the resource folder -> Create DB folder -> Create migration folder -> Create database file with Version_SubVersion__Name(As defined below).
Normally this happens in following cases,
Path is not proper try using set locations param value.
db.migrate folder not contain any file.
Check name of file : V1_1__(short_desc)
Try to run using, mvn compile flyway:migrate
In my case i already place sql file over there but still it gives same error,
Basically i place this sql file using copy paste from somewhere.
When i try to add one new file on same place using IDE (Intellij : Right click on migration folder -> new -> Flyway migration -> versioned migration), then it ask me(warning) about some delicate allowance(normally we mention in database configuration i also place there still), and it start working.
Flyway requires at-least one script, disable it until u need it by using following command in application.properties file
spring.flyway.enabled=false
I believe that Flyway requires at least one migration script to initialize. Try adding a simple sql creation script into your migration folder and give it another try. Alternatively you can disable the flyway dependency until you need it.
I had a similar error, and solved it as follows: I added these commands
spring.flyway.baselineOnMigrate=true
spring.flyway.check-location=true
spring.flyway.locations=classpath:db/migration
spring.flyway.schemas=public
spring.flyway.enabled=true
to application.properties
I had the same issue. When I created the directory, I simply typed db.migration - the same way one would do with package names. InteliJ will display both db.migration and db/migration directories as db.migration, so while it may look correct in IntelliJ, flyway requires the latter.
Even when having your migration files in the db/migration folder, flyway won't detect it.
Then you will have to fix this by explicitly setting the locations in your application.properties (or appliocation.yml) by adding:
spring.flyway.locations=classpath:db/migration
N.B: Also you need to have at least one script to initialize flyway, you can even put an empty one. But you need to have at least one script
As #Guy suggested in his answer, I created an SQL file in the migration folder and left it empty. Named v1_0__mock_flyway.sql in the migration folder classpath:db/migration. Error solved.
If you have tried everything above and it still does not apply the migrations.
Be sure you have followed the steps in the previous answers
A db.migration folder exists in your resources folder
The sql scripts are named with respect to the correct naming convention, such as V1__init.sql
The following config exists in your application.properties/application.yml
spring.flyway.locations=classpath:db/migration
Do a clean build
-> mvn clean
Then restart your spring boot app, this worked for me.
When i try and to start Liquibase via:
JdbcConnection liquibaseConnection = new JdbcConnection(connection);
Liquibase liquibase = new Liquibase("mychanges.xml",
new ClassLoaderResourceAccessor(),liquibaseConnection);
liquibase.update("dev");
When it is going to update i get this exception
liquibase.exception.ChangeLogParseException: Error Reading Migration File: Found 2 files that match mychanges.xml
And is caused by:
Caused by: java.io.IOException: Found 2 files that match mychanges.xml
This seems strange because when i look in the war file it just contains one mychanges.xml
Ive tried renaming it and to move it to another location.
I do not understand why it is giving me this excepton. plees help
I found it myself. The exception thrown was not correct.
It actually meant that the file could not be found.
Very strange exception for this case.
With this i found out that my classpath was kinda broken.
In my case the folder path to the update sql file had non-ASCII characters in it (exp: éáű). Moving the update file into an ASCII only folder path worked.
This is with Liquibase 4.2.0 (2020-11-13 release).
[Rant]
Imagine supporting Unicode in 2020.
Liquibase team: nah
[/Rant]
I had the same problem and found the following reason in ClassLoaderResourceAccessor.java:
Enumeration<URL> resources = classLoader.getResources(path);
Consequently your xml must be part of the classpath, not a path in your filesystem or something like this.
Check your pom.xml .There can be extra dependency in your pom.xml or some unused projects in your pom.xml .
Also the projects you are importing using pom have same database file names.
I solved this problem by removing extra dependency from pom.xml
I'm using Jenkins 1.6.20 (Git Client Plugin 1.18.0, Git Plugin 2.4.0) to get the Java application code from bitbucket.org and deploy it to Apache Tomcat 8.0.23.
The error appears while deploying and looks like:
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'requestMappingHandlerMapping' defined in class path resource [org/spr$
public java.util.List by.ipps.accounting.ws.PositionWS.getEmployeePost(java.lang.Long)
to {[/positionListJson/{id}],methods=[GET],params=[],headers=[],consumes=[],produces=[application/json],custom=[]}: There is already 'resourceWS' bean method
public by.ipps.accounting.model.Employee.EmployeePost by.ipps.accounting.ws.ResourceWS.getEmployeePost(java.lang.Long) mapped.
bla-bla-bla ... so many errors ...
Caused by: java.lang.IllegalStateException: Ambiguous mapping found. Cannot map 'positionWS' bean method
public java.util.List by.ipps.accounting.ws.PositionWS.getEmployeePost(java.lang.Long)
to {[/positionListJson/{id}],methods=[GET],params=[],headers=[],consumes=[],produces=[application/json],custom=[]}: There is already 'resourceWS' bean method
public by.ipps.accounting.model.Employee.EmployeePost by.ipps.accounting.ws.ResourceWS.getEmployeePost(java.lang.Long) mapped.
The problem is that the class (with annotation #Controller) PositionWS with method getEmployeePost was renamed to ResourceWS a week ago, so exists no more, so I should not get this error.
To fix this I have to create a blank PositionWS controller (with no methods in it), commit & push that to bitbucket (and delete (cus i really don't need it) later and commit & push).
It seems to be like a bug in any of the applications I use. I can't find out in which app there is a bug to report it. Tell me please, if anyone faced such problems.
The heart of the issue was in incorrect configuration of Jenkins, it was my fault.
When I was configuring Jenkins I set maven goal as "install", but it must be "clean install". According to this Jenkins never deleted old files and kept them, so got a lot of issues of different kinds and with different log messages.
Due to Jenkins working specialty it downloads project files and try to assemble it on path /var/lib/jenkins/jobs/<projectName>/workspace/target/.
So I've drop the data in this folder and afterwards set maven goal to "clean install" and that fixed the issue.
I'm getting quite a specific error while trying to embed pure Spring (not Spring Boot) application with liquibase in an uberjar. As soon as SpringLiquibase bean is initialized, it starts looking for something i don't understand:

I'm aware of Liquibase-Package entry in MANIFEST.MF and filling it using shade plugin (though i don't understand what use does it have) and putting it using shade plugin, but it doesn't give any effect. What is liquibase looking for and how can i overcome those errors?
According to this issue, this issue would be fixed if you create a src/main/webapp folder:
Incidentally, the root cause is that no src/main/webapp folder exists. As a work around you could create one or set a value in #WebAppConfiguration that points to classpath: folder that actually exists.
i`m getting NoClassDefintion found error in my application even though i had the associated jars in my lin folder of my ear the error is
java.rmi.RemoteException: EJB Exception: ; nested exception is:
java.lang.NoClassDefFoundError: com/sun/rave/web/ui/model/Option
Note i had added the same user library to my eclipse its not showing any compilation error this error is only at runtime ......!!!!!
I haven't used EJBs for a while but I seem to remember having to set up the classpath differently for EJBs. I think you have to set it in the manifest.mf file in the EJB jar.
A quick Google turns up this thread, suggesting you need to put:
Class-Path: jar1.jar, jar2.jar
In your manifest.mf file.
You might also find this page (scroll right down to the bottom) and this one (search for "Class-Path") helpful.
