Hi,
I hav postgresql 15 installed in my windows computer.
I have maven java project, wich works temporarly in Eclipse, but mvn
install did'nt work.
Now it works, but I have got error -
Exception in thread "main" java.lang.NoSuchMethodError:
'org.postgresql.core.Encoding
org.postgresql.core.BaseConnection.getEncoding()'
at
org.postgresql.jdbc2.AbstractJdbc2ResultSet.getString(AbstractJdbc2ResultSet.java:1889)
at
org.postgresql.jdbc2.AbstractJdbc2ResultSet.getTimestamp(AbstractJdbc2ResultSet.java:438)
at
org.postgresql.jdbc2.AbstractJdbc2ResultSet.getTimestamp(AbstractJdbc2ResultSet.java:2406)
at backendproject.BackendMain.main(BackendMain.java:64)
backendproject.BackendMain.main(BackendMain.java:64) line is following -
Timestamp oldest_timestamp = resultSet.getTimestamp("oldest_timestamp");
Query from Java is following -
String query = "SELECT timestamp AS oldest_timestamp FROM mushrooms";
PreparedStatement statement = connection.prepareStatement(query);
ResultSet resultSet = statement.executeQuery();
And pom.xml contains -
<dependencies>
<dependency>
<groupId>org.postgis</groupId>
<artifactId>postgis-jdbc</artifactId>
<version>1.3.3</version>
</dependency>
<dependency>
<groupId>org.postgresql</groupId>
<artifactId>postgresql</artifactId>
<version>42.2.0</version>
</dependency>
and mvn install gives -
[INFO] --- dependency:3.6.0:copy-dependencies (copy-dependencies) @
backendproject --- [INFO] Copying postgis-jdbc-1.3.3.jar to

What is reason of this error and how to resolv it ?
