I'm currently working in my company developing an API in Spring Boot with an Oracle database, the problem is that we use liquibase to create the database, and when I try to use the command:
mvn liquibase:update -Dliquibase.url="jdbc:oracle:thin:#..." -Dliquibase.username="xxx" -Dliquibase.password="xxx" -Dinterface-user="xxx" -Dtablespace-tablas="xxx" -Dtablespace-indices="xxx" -Dstorage-tablas="xxx" -Dstorage-indices="xxx"
It returns me this error:
Plugin .url=jdbc:oracle:thin or one of its dependencies could not be resolved: Failure to find .url=jdbc:oracle:jar:thin in https://maven.oracle
.com was cached in the local repository, resolution will not be reattempted until the update interval of maven.oracle.com has elapsed or updates are for
ced -> [Help 1]
I think it is related with the dependency ojdbc8 from oracle but I can't figure out how to make it work.
I know that all the credentials for the database and everything are correct as I can totally use them to connect to the database with a db manager.
Here is my dependency in pom.xml:
<dependency>
<groupId>com.oracle</groupId>
<artifactId>ojdbc8</artifactId>
<version>19.3</version>
</dependency>
Right now I've tried these things:
Downloading the dependency from maven repo (https://mvnrepository.com/artifact/com.oracle.ojdbc/ojdbc8/19.3.0.0) and installing it locally using the command: mvn install:install-file -Dfile=./ojdbc8.jar -DgroupId=com.oracle -DartifactId=ojdbc8 -Dversion=19.3 -Dpackaging=jar.
This supposedly installed the dependency locally, but still does not work.
Adding the oracle server to the dependency repos in maven config, following this oracle guide
(https://docs.oracle.com/middleware/1213/core/MAVEN/config_maven_repo.htm#MAVEN9016)
With this second change I manage to get a different error:
Plugin .url=jdbc:oracle:thin or one of its dependencies could not be resolved: Could not find artifact .url=jdbc:oracle:jar:thin in maven.oracle
.com (https://maven.oracle.com) -> [Help 1]
Could you help me find what am I doing wrong or something that I might be missing? Thanks!
You need to use the follow GAV for downloading the JDBC driver from central maven. Refer to Maven guide for more details
<dependency>
<groupId>com.oracle.database.jdbc</groupId>
<artifactId>ojdbc8</artifactId>
<version>19.3.0.0</version>
</dependency>
In the end, the main problem was that I was using the embedded console of IntelliJ and It wasn't working that way, I switched to cmd and it worked...
I am working on a Spring Boot Batch example with MongoDB and I have already started the mongod server.
When I launch my application, I am getting the error below.
Any pointers for this issue?

Just add : #SpringBootApplication(exclude = {DataSourceAutoConfiguration.class })
works for me.
I was getting same error I tried with #EnableAutoConfiguration(exclude=...) didn't work.
For those that are wondering where to add #SpringBootApplication(exclude = {DataSourceAutoConfiguration.class }), as it has been asked by user as well. You need to add it to the main Application class which is under src>main>java. By default it is set to #SpringBootApplication
check your application.properties
changing
spring.datasource.driverClassName=com.mysql.jdbc.Driver
to
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
worked for me. Full config:
spring.datasource.url=jdbc:mysql://localhost:3306/db
spring.datasource.username=
spring.datasource.password=
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.jpa.database-platform = org.hibernate.dialect.MySQL5Dialect

Your problem is the dependency of spring batch spring-boot-starter-batch that has a spring-boot-starter-jdbc transitive maven dependency.
Spring Batch is a framework for building reliable and fault tolerance enterprise batch jobs. It supports many features like restarting a failed batch, recording the status of the batch execution and so on. In order to achieve that Spring Batch uses a database schema to store the status of the registered jobs, the auto-configuration already provides you the basic configuration of the required data source and it is this configuration that requires the relational database configuration.
To solve this you must include some database driver like mysql, h2, etc. to configure the url.
Update:
Just for getting start you can configure your application.yml like below:
spring:
datasource:
driver-class-name: org.h2.Driver
url: jdbc:h2:mem:localhost;DB_CLOSE_ON_EXIT=FALSE
username: admin
password:
and of course in your pom.xml include the h2 dirver like this:
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

The motivation, because you can not use mongo for this purpose, is that the usage of mongo is provided only for item readers and writers and not for managing the internal database of Spring Batch that is an internal schema, not a business schema. The query is plain SQL query and the internal abstraction relies on a relational database. It is necessary to have a database with ACID capability because every batch reads and writes a chunk of work and saves that information in order to restart the job. A NoSql solution is not suitable for this.
At the end you have configured a relational database in order to prepare Spring Batch for internal capability, the internal abstraction does not rely on mongo only on jdbc. Then mongo can be used but for the business side of the batch via item reader/writer.
I hope that this can help you to clear your doubts.
Root Cause
The JPA (Java persistence API) is a java specification for ORM (Object-Relational Mapping) tools. The spring-boot-starter-data-jpa dependency enables ORM in the context of the spring boot framework.
The JPA auto configuration feature of the spring boot application attempts to establish database connection using JPA Datasource. The JPA DataSource bean requires database driver to connect to a database.
The database driver should be available as a dependency in the pom.xml file. For the external databases such as Oracle, SQL Server, MySql, DB2, Postgres, MongoDB etc requires the database JDBC connection properties to establish the connection.
You need to configure the database driver and the JDBC connection properties to fix this exception Failed to configure a DataSource: ‘url’ attribute is not specified and no embedded datasource could be configured. Reason: Failed to determine a suitable driver class.
application.properties
spring.autoconfigure.exclude=org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration
application.yaml
spring:
autoconfigure:
exclude: org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration
By Programming
#SpringBootApplication(exclude = {DataSourceAutoConfiguration.class })
Not to the point of the question (can be related though), but, if you bootstrap a new project and wondering why do you get the same error, it may come from the artifactId of spring-boot-starter-data-jpa in the dependency section. I gave the dependency below. You will need to define the database to get rid of this.
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
Excluding the DataSourceAutoConfiguration.class worked for me:
#SpringBootApplication(exclude = {DataSourceAutoConfiguration.class })
I had the same issue resolved by add <scope>provided</scope>
<dependency>
<groupId>org.springframework.boot</groupId>

This link helped.
Spring Boot auto-configuration tries to configure beans
automatically based on the dependencies added to the classpath. And
because we have a JPA dependency (spring-data-starter-jpa) on our classpath, it tries to configure it.
The problem: Spring boot doesn't have the all the info needed to configure the JPA data source i.e. the JDBC connection properties.
Solutions:
provide the JDBC connection properties (best)
postpone supplying connection properties by excluding some AutoConfig classes (temporary - should be removed eventually)
The above link excludes the DataSourceAutoConfiguration.class with
#SpringBootApplication(exclude={DataSourceAutoConfiguration.class})
But this didn't work for me. I instead, had to exclude 2 AutoConfig classes:
#SpringBootApplication(exclude = {DataSourceAutoConfiguration.class, XADataSourceAutoConfiguration.class})
It can be that your resources directory is not added to classpath when creating a project via Spring Initializr. So your application is never loading the application.properties file that you have configured.
To make a quick test if this is the case, add the following to your application.properties file:
server.port=8081
Now when running your application you should see in the spring boot console output something like this:
INFO o.s.b.w.e.tomcat.TomcatWebServer - Tomcat started on port(s): **8081** (http) with context path ''
If your port is still default 8080 and not changed to 8081, your application.properties files is obviously not loading.
You can also check if your application runs with gradle bootRun from command line. Which most likely will be work.
Solution:
Close IntelliJ, then inside your project folder delete the ".idea" folder
Reimport your project to IntelliJ like following: "Import Project" -> "select ONLY your build.gradle file to import". (IntelliJ will automatically grab the rest)
build and run your application again
See official answer by IntelliJ Support:
IDEA-221673
The following worked for 2021 spring-boot release 2.5.0
If you have as minimum these entries in your application.properties
spring.datasource.url=jdbc:mysql://localhost:3306/db
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
And these dependencies in your pom.xml
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
You should not have this error:
Failed to configure a DataSource: 'url' attribute is not specified and no embedded datasource could be configured.
Reason: Failed to determine a suitable driver class
It was the IDE in my case
No matter if you are using eclipse or intellij, application must run over linux in real environments. So to validate if is an IDE problem, run your app using shell
mvn spring-boot:run
If it starts without error, the problem is in your IDE
Eclipse
Eclipse IDE for Enterprise Java and Web Developers
Version: 2021-03 (4.19.0)
Build id: 20210312-0638
On my case I was running the project with right click on the classic Application.java inside of spring boot project , then run as java application
After hours of researching, the solution was:
right click on the root spring boot project, then run as java application. Eclipse shows me several class with main methods. I choose my Application.java and then run
Long Explanation
If you check the exact method error DataSourceProperties.determineDriverClassName you will see that just driverClassName or dirver-class-name and url is required.
“Failed to configure a DataSource” error. First, we fixed the issue by defining the data source. Next, we discussed how to work around the issue without configuring the data source at all.
https://www.baeldung.com/spring-boot-failed-to-configure-data-source
I have added this annotation on the main class of my spring boot application and everything is working perfectly
#SpringBootApplication(exclude = {DataSourceAutoConfiguration.class })
I faced the same issue in my code, adding this code in Application.java file helped me out-
#SpringBootApplication(exclude = { DataSourceAutoConfiguration.class, DataSourceTransactionManagerAutoConfiguration.class})
For spring boot version 2.X.X below configuration worked for me.
spring.datasource.url=jdbc:mysql://localhost:3306/rest
spring.datasource.username=
spring.datasource.password=
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.jpa.database-platform = org.hibernate.dialect.MySQL5Dialect
spring.jpa.generate-ddl=true
spring.jpa.hibernate.ddl-auto = update
Old jdbc driver is deprecated. The new one is mentioned on above configuration.
Please use the same and restart the project.
It can be because you have jpa dependendencies and plugins...
just comment it if not use(build.gradle or pom file)
e. g.
// kotlin("plugin.jpa") version "1.3.61"
// implementation("org.springframework.boot:spring-boot-starter-data-jpa")
An optiona Solution if already tested all last answers
If you have an error like title
And validated .properties connection string is correct.
Then add this code block about maven plugin in your .pom file
...
</dependency>
</dependencies>
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-resources-plugin</artifactId>
<version>3.1.0</version>
</plugin>
...
And Update project. Works for me!!!
I hope this help you to.
This steps you the found in this link page.
Failed to execute goal org.apache.maven.plugins:maven-resources-plugin:3.2.0:resources
https://exerror.com/failed-to-execute-goal-org-apache-maven-pluginsmaven-resources-plugin3-2-0resources/
And here:
Maven clean install: Failed to execute goal org.apache.maven.plugins:maven-resources-plugin:3.2.0:resources
It's happening because the #valerio-vaudi said.
Your problem is the dependency of spring batch
spring-boot-starter-batch that has a spring-boot-starter-jdbc
transitive maven dependency.
But you can resolve it set the primary datasource with your configuration
#Primary
#Bean(name = "dataSource")
#ConfigurationProperties(prefix = "spring.datasource")
public DataSource getDataSource() {
return DataSourceBuilder.create().build();
}
#Bean
public JdbcTemplate jdbcTemplate(DataSource dataSource) {
return new JdbcTemplate(dataSource);
}
If you're using Gradle, rebuild Gradle can solve this problem.
Add this annotation in main java file
#EnableAutoConfiguration(exclude=DataSourceAutoConfiguration.class)
So, I am had with similar problem, and this link helpfull
https://www.yawintutor.com/failed-to-configure-a-datasource-failed-to-determine-a-suitable-driver-class/
What I understood is that preset of project need to have a "RDBMS Database" and a "In Memory Database"
RDBMS Database
mysql
Postgres
oracle
SQL server
In Memory Database
H2 Database
HSQL Database
Derby Database
So, when I selected this preset, all worked great
If datasource is defined in application.resources, make sure it is locate right under src/main and add it to the build path.
If you have a JPA dependency in your pom.xml then just remove it. This solution worked for me.
For me the resource folder was getting excluded on a maven update/build. I went to Build Path>Source and found that src/main/resources have "Excluded **". I removed that entry (Clicked on Excluded **>Remove>Apply and Close).
Then it worked fine.
If you are using YAML for configuration, then it might be indentation problem. Thoroughly check the YAML files.
It simply means you have downloaded a spring starter code with database dependency without configuring your database, So it doesn't know how to connect. For Spring boot version 2.18 do the following steps to fix it.
Create a database for the driver you have downloaded ie mysql/mongo etc.
In your applications.properties file add the db connection info. Sample is given for mysql if your db is mongo change it for mongo.
spring.datasource.url=jdbc:mysql://localhost:3306/db_name_that_you_created
spring.datasource.username=your_db_username_here
spring.datasource.password=your_db_pass_here
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.jpa.database-platform = org.hibernate.dialect.MySQL5Dialect
spring.jpa.generate-ddl=true
spring.jpa.hibernate.ddl-auto = update
Reboot the server it will be running.
Inside pom.xml file always keep the updated spring framework version.
I had created a project with spring framework version 2.5.5 and it was working fine that time. After a couple of months, I found that it is not working correctly. Then I put the latest version of the spring framework. Then it works.
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>Updated version</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>
Check spring profile also, by default it goes for 'default' profile, if your application properties have different profiles like the test, prod, etc then you need to set up it. for eclipse set environment variable as
name=spring.profiles.default, value=test
I had the same issue and tried all suggestions above, but didnt work out. I am posting my answer for furture readers. Before it was working fine but somehow it apeared again. I resolved this issue by removing some unnecessary plugnins and depencies from pom.xml
First of all, I changed default packaging type to jar (Spring Boot Initializer gives pom in packaging)
<packaging>jar</packaging>
I added unintentional some plugins:
<plugin>
<artifactId>maven-war-plugin</artifactId>
<configuration>
<attachClasses>true</attachClasses>
<webXml>target/web.xml</webXml>
<webResources>
<resource>
<directory>src/main/webapp</directory>
<filtering>true</filtering>
</resource>
</webResources>
</configuration>
</plugin>
I hope my answer will help someone.
This one worked for me, for MySQL:
(Application properties)
spring.datasource.url=jdbc:mysql://localhost:3306/db?useSSL=false&useUnicode=true&useJDBCCompliantTimezoneShift=true&
useLegacyDatetimeCode=false&serverTimezone=UTC
spring.datasource.username=root
spring.datasource.password=admin
spring.jpa.hibernate.ddl-auto=create
spring.jpa.show-sql=true
I removed an obsolete dependency on mybatis in the pom.xml to get mine running.
