Hello!
I’m using liquibase docker container:

docker run --rm -v I:\Projects\Liquibase:/liquibase/changelog liquibase/liquibase --defaultsFile=/liquibase/changelog/configs/liquibase.properties status
I’m trying to connect with the local Oracle database and I’m getting the following error:
Connection could not be created to jdbc:oracle:thin:@localhost:1521:xe with driver oracle.jdbc.OracleDriver.  IO Error: The Network Adapter could not establish the connection
liquibase.properties file:
url: jdbc:oracle:thin:@localhost:1521:xe
username: men
password: 1
But connecting via SQL*Plus or SQL Developer is successful.
>sqlplus men/1@localhost:1521/xe
Connected to:
Oracle Database 11g Express Edition Release 11.2.0.2.0 - Production
>tnsping localhost:1521/xe
Used HOSTNAME adapter to resolve the alias
Attempting to contact (DESCRIPTION=(CONNECT_DATA=(SERVICE_NAME=xe))(ADDRESS=(PROTOCOL=TCP)(HOST=127.0.0.1)(PORT=1521)))

What am I doing wrong?
              
Hello,
Specify the classpath for the used oracle driver in your liquibase.properties file.
Make sure that you’re using a compatible driver:JDBC and UCP Downloads page
Try to do it like in this link : Managing Database Objects using Oracle | Liquibase Docs
Regards,

Ahmed.
classpath: /liquibase/changelog/OJDBC/8/ojdbc8.jar
Oracle Database 11g Express Edition Release 11.2.0.2.0 + JDK 8 + ojdbc8
Step1 - 
I still get the error.
              
Hello,
Try to check the listener is up or down.

I think that you have issue  establishing DB connection through network.

Install SQL developper to check if your DB is accessed remotely or not.

Ahmed.

Make sure it’s working before save with clicking on “test” button.
2- Here is the content of my liquibase.properties :
driver: oracle.jdbc.OracleDriver

classpath: ./ojdbc8.jar

url: jdbc:oracle:thin:@localhost:1521:XE

username: hr

The ojdbc8.jar was downloaded from this link :

3- Here it’s my changelog file test.xml:

If you’re running it in docker, it’ll try to use the internal container loop back address and will fail connecting to the host. You’ll need to specify an external IP address.

Thank you, erinlkolp!

You were right. Your advice helped me solve the problem.
Му liquibase.properties:
driver: oracle.jdbc.OracleDriver
classpath: /liquibase/changelog
url: jdbc:oracle:thin:@192.168.1.80:1521:xe
username: men
password: 1
changeLogFile: mychangelog.oracle.sql
Also, for Oracle 11g, I had to upgrate the time zone file, because I got the error:
Starting Liquibase at 16:31:20 (version 4.3.5 #62 built at 2021-04-29 18:31+0000)
Unexpected error running Liquibase: liquibase.exception.DatabaseException: 
liquibase.exception.DatabaseException: Connection could not be created 
to jdbc:oracle:thin:@192.168.176.1:1521:xe with driver oracle.jdbc.OracleDriver.  
ORA-00604: error occurred at recursive SQL level 1
ORA-01882: timezone region not found
I used this instruction: Steps to Upgrade Time Zone File and Timestamp with Time Zone Data
I took the time zone file timezlrg_31.dat and timezone_31.dat from oracle-database-xe-18c-1.0-1.x86_64  image and put it in $ORACLE_HOME/oracore/zoneinfo.
Here are next my steps:
