Configuration java.lang.NoClassDefFoundError apache commons配置错误

我正在尝试为Oracle ADF项目创建一个共享库。我创建了一个util，用于读取属性的外部文件并加载到ADF服务中。因此，我为这个共享项目创建了一个maven项目，它构建了一个jar。当添加这个库时，我在编译时没有问题。我能够将新类导入到consume ADF服务项目中。当我部署新的ear时。在测试使用ConfigService读取外部属性文件的行时，我遇到以下异常：

配置服务：

public class ConfigService {
    private static ADFLogger logger = ADFLogger.createADFLogger(ConfigService.class); 
    private FileBasedConfiguration configService;
    private static String DEFAULT_CONFIG_FILE_PATH="C:\\com.aar.webservices.common.config\\application.properties";
    private String filePath;

    public ConfigService(){
        super();
    }

    /**

    public FileBasedConfiguration getConfigService() {
        Parameters params = new Parameters();
        if(this.configService == null) {// Check if the singleton instance of config service is initialized ; If not initialize.
            try {
                File propertyFile = new File(DEFAULT_CONFIG_FILE_PATH);
                FileBasedConfigurationBuilder<FileBasedConfiguration> builder =
                        new FileBasedConfigurationBuilder<FileBasedConfiguration>(PropertiesConfiguration.class)
                                .configure(params.properties().setFile(propertyFile));

                this.configService = builder.getConfiguration();
                logger.info("Successfully initialized property bean.");
            } catch (ConfigurationException cex) {
                logger.severe("Loading of Config service failed!");
                logger.severe(cex);
            }
