MyBatis generator with Java is not working

MyBatis generator doesn't want to generate the code for me. I use an Eclipse IDE for that. At first I suspect targetProject property, but I specify the current folder for that and actually there is no result as well.

I work OK with the same xml conf from the command-line.

I think that I have to provide into my Java code the outputFolder some how, I tried prop.setProperty("generated.source.dir", System.getProperty("user.dir")); but it doesn't work.

So, any suggestions will be appreciated.

Here is my java code for generation

public class GeneratorMyBatis {

    public static void main(String args[]) {
        try {
            generate();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    private static void generate() throws Exception {
        System.out.println("Working Directory = " + System.getProperty("user.dir"));
        List<String> warnings = new ArrayList<String>();
        boolean overwrite = true;
        File configFile = new File("src//main//resources//mybatis//generator//config//generatorConfig.xml");
        Properties prop = new Properties();
        prop.setProperty("generated.source.dir", System.getProperty("user.dir"));
        ConfigurationParser cp = new ConfigurationParser(prop, warnings);
        Configuration config = cp.parseConfiguration(configFile);
        config.validate();
        DefaultShellCallback callback = new DefaultShellCallback(overwrite);
        ProgressCallback progress = new VerboseProgressCallback();
        MyBatisGenerator myBatisGenerator = new MyBatisGenerator(config, callback, warnings);
        myBatisGenerator.generate(progress);
    }
}

My configuration xml file

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE generatorConfiguration
        PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"
        "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">

<generatorConfiguration>

    <context id="MyTables" targetRuntime="MyBatis3">
        <jdbcConnection driverClass="com.mysql.jdbc.Driver"
                        connectionURL="jdbc:mysql://localhost:3306/my_db"
                        userId="root"
                        password="root">
        </jdbcConnection>

        <javaTypeResolver >
            <property name="forceBigDecimals" value="false" />
        </javaTypeResolver>

        <javaModelGenerator targetPackage="model" targetProject="\">
            <property name="enableSubPackages" value="true" />
            <property name="trimStrings" value="true" />
        </javaModelGenerator>

        <sqlMapGenerator targetPackage="xml"  targetProject="\">
            <property name="enableSubPackages" value="true" />
        </sqlMapGenerator>

        <javaClientGenerator type="XMLMAPPER" targetPackage="dao"  targetProject="\">
            <property name="enableSubPackages" value="true" />
        </javaClientGenerator>

        <table schema="my_db" tableName="assignment" domainObjectName="Assignment" >
            <property name="useActualColumnNames" value="true"/>
            <generatedKey column="id" sqlStatement="MySql" identity="true" />
        </table>
    </context>
</generatorConfiguration>

I got this log messages

All in all I found out the how to fix the issue.

MyBatis generates the all necessary staff, but puts it into the disk root, like D:\ for example.

To configure on java targetProject and targetPackage, you have to set them into the Configuration object. Something like this:

Configuration config = cp.parseConfiguration(configFile);
config.getContexts().get(0).getJavaModelGeneratorConfiguration().setTargetProject(TARGET_PROJECT_PATH);
config.getContexts().get(0).getJavaModelGeneratorConfiguration().setTargetPackage(MODEL_TARGET_PACKAGE);
config.getContexts().get(0).getSqlMapGeneratorConfiguration().setTargetProject(TARGET_PROJECT_PATH);
config.getContexts().get(0).getSqlMapGeneratorConfiguration().setTargetPackage(XML_MAPPER_TARGET_PACKAGE);
