SQLite does not work after building a Java project

Good day! I do the project in IDEA with use of SQLite. In the development environment, the project is quite working, but after building on maven a database file is created and this is where it ends. It weighs 0 bytes, when opened via SqliteBrowser does not find any 1 table, respectively.

Here is the pom.xml file:

<?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" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>MoneyManager</groupId> <artifactId>MoneyManager</artifactId> <version>1.0-SNAPSHOT</version> <packaging>jar</packaging> <build> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-jar-plugin</artifactId> <version>2.4</version> <configuration> <archive> <manifestFile> src/main/java/META-INF/MANIFEST.MF </manifestFile> <manifest> <addClasspath>true</addClasspath> <mainClass>Main</mainClass> <packageName>MoneyManager</packageName> <addClasspath>true</addClasspath> <classpathPrefix>lib/</classpathPrefix> </manifest> </archive> </configuration> </plugin> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <version>2.3.2</version> <configuration> <source>1.7</source> <target>1.7</target> <encoding>UTF-8</encoding> </configuration> </plugin> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-dependency-plugin</artifactId> <version>2.5</version> <executions> <execution> <id>copy-dependencies</id> <phase>package</phase> <goals> <goal>copy-dependencies</goal> </goals> <configuration> <includeScope>compile</includeScope> <outputDirectory>${project.build.directory}/lib</outputDirectory> </configuration> </execution> </executions> </plugin> </plugins> </build> <dependencies> <!-- https://mvnrepository.com/artifact/org.xerial/sqlite-jdbc --> <dependency> <groupId>org.xerial</groupId> <artifactId>sqlite-jdbc</artifactId> <version>3.8.11.2</version> </dependency> <dependency> <groupId>commons-codec</groupId> <artifactId>commons-codec</artifactId> <version>1.10</version> </dependency> <!-- https://mvnrepository.com/artifact/com.toedter/jcalendar --> <dependency> <groupId>com.toedter</groupId> <artifactId>jcalendar</artifactId> <version>1.4</version> </dependency> <!-- https://mvnrepository.com/artifact/com.lowagie/itextpdf --> <dependency> <groupId>com.lowagie</groupId> <artifactId>itext</artifactId> <version>4.2.1</version> </dependency> </dependencies> </project> 

here is the java code:
