I am working with my Spring Boot Application.
I have got some error:
java.nio.file.NoSuchFileException: C:\Users\thomas\.m2\repository\com\mchange\c3p0\0.9.5.5\mchange-commons-java-0.2.19.jar

Description:
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
Action:
Consider the following:
If you want an embedded database (H2, HSQL or Derby), please put it on the classpath.
If you have database settings to be loaded from a particular profile you may need to activate it (no profiles are currently active).
Disconnected from the target VM, address: '127.0.0.1:63565', transport: 'socket'

As I see the JAR file name was changed fromĀ mchange-commons-java-0.2.19.jar toĀ c3p0-0.9.5.5.jar.
Expected file path:
C:\Users\thomas\.m2\repository\com\mchange\c3p0\0.9.5.5\mchange-commons-java-0.2.19.jar
Found file path:
C:\Users\thomas\.m2\repository\com\mchange\c3p0\0.9.5.5\c3p0-0.9.5.5.jar
Hints:
- it looks like bugĀ caused by changesĀ againstĀ detected vulnerabilities inĀ Mchange Commons JavaĀ Ā»Ā 0.2.19Ā (check this link)
- if you useĀ hibernate-c3p0, check latest versionsĀ and site notification:
Note:Ā This artifact was moved to:Ā org.hibernate.ormĀ Ā»Ā hibernate-c3p0Ā Ā» 6.0.0.CR2
Screenshot with changed name:
Solution
You can try to:
- UpgradeĀ
hibernate-c3p0
https://mvnrepository.com/artifact/org.hibernate/hibernate-c3p0 - or:Ā do not use:
<dependency> <groupId>org.hibernate</groupId> <artifactId>hibernate-c3p0</artifactId> <version><!-- used version here ... --></version> <scope>compile</scope> </dependency>
