问题描述
我们将SCDF（版本2.6.1）与定义Maven设置的环境变量一起使用：
MAVEN_LOCALREPOSITORY: custom-local-repo
MAVEN_REMOTEREPOSITORIES_MTREPO_URL: url
MAVEN_REMOTEREPOSITORIES_MTREPO_AUTH_USERNAME: user-name
MAVEN_REMOTEREPOSITORIES_MTREPO_AUTH_PASSWORD: password
从maven下载在注册简单任务的过程中正确进行，本地存储库已满，但是当我们创建任务时，会收到错误消息：

也许问题出在这里
public JdbcDataflowTaskExecutionMetadataDao(DataSource dataSource,datafieldMaxValueIncrementer incrementer) {
this.incrementer = incrementer;
this.jdbcTemplate = new NamedParameterJdbcTemplate(dataSource);
this.objectMapper = new ObjectMapper();
SimpleModule module = new SimpleModule();
module.addDeserializer(Resource.class,new ResourceDeserializer(new AppResourceCommon(new MavenProperties(),new DefaultResourceLoader())));
this.objectMapper.registerModule(module);
this.objectMapper.addMixIn(Resource.class,ResourceMixin.class);
this.objectMapper.addMixIn(AppDeFinition.class,AppDeFinitionMixin.class);
this.objectMapper.addMixIn(AppDeploymentRequest.class,AppDeploymentRequestMixin.class);
this.objectMapper.configure(SerializationFeature.FAIL_ON_EMPTY_BEANS,false);
this.dataSource = dataSource;
}
正是在这里：
module.addDeserializer(Resource.class,new DefaultResourceLoader())));
AppResourceCommon获取一个具有默认本地存储库值的MavenProperties对象-$ {user.home} /。M2 / repository /
也许还有其他东西吗？
