liquibase: changelogSync дает исключение NullPointerException

0 голосов
/ 07 декабря 2018

Я пытаюсь загрузить данные в oracle db с помощью changelogSync и получаю исключение nullpointer.Моя версия с жидкой фазой - 3.6.2, и я использую maven для выполнения задач с жидкостной базой.Эти данные я извлек из другой базы данных, используя generateChangeLog в формате xml.

Пожалуйста, дайте мне знать, если я что-то делаю не так.

mvn -X clean liquibase: changelogSync -f backup_pom.xml

Вот мой pom: 

<project>
  <modelVersion>4.0.0</modelVersion>

ОБНОВЛЕНО: Я неправильно использовал changelogSync, но даже если я запускаю цель обновления, я получаю ту же ошибку.Я хотел бы подчеркнуть, что XML-файл outputChangelog не был в правильном формате xml и имел специальные символы.Поэтому мне пришлось удалить их вручную, прежде чем запускать цель любого другого плагина.Но после удаления этого специального символа я получаю исключение NullPointerException.

Первая ошибка в том, что команда changelogSync не будет загружать данные в базу данных.Эта команда предназначена для использования, когда вы внесли изменения в базу данных другим способом (с помощью разработчика Oracle SQL или студии управления SQL Server или чего-то подобного), и у вас есть соответствующие изменения в файле changelog.xml, и вы хотите убедиться, чточто таблица DATABASECHANGELOG отражает синхронизацию двух.

Если в файле changelog.xml есть что-то, что вы хотите развернуть в базе данных, вы должны использовать команду liquibase update.

Тем не менее, я не уверен, почему вы получаете это исключение нулевого указателя.У рассматриваемой строки кода есть несколько мест, где это может быть сгенерировано.Возможно, таблица DATABASECHANGELOG вообще не существует или существует, но не имеет правильных столбцов.

https://github.com/liquibase/liquibase/blob/8ee4607c7a0c99c5de9538c0ca850473b300576e/liquibase-core/src/main/java/liquibase/changelog/StandardChangeLogHistoryService.java#L127

    if (!(this.getDatabase() instanceof SQLiteDatabase)) {
        DataType type = changeLogTable.getColumn("LIQUIBASE").getType();
        if (type.getTypeName().toLowerCase().startsWith("varchar")) {
            Integer columnSize = type.getColumnSize();
            liquibaseColumnNotRightSize = (columnSize != null) && (columnSize < 20);
        } else {
            liquibaseColumnNotRightSize = false;
        }
    }
