Question

我在postgresql-db上运行maven的liquibase-plugin时遇到问题。当尝试运行liquibase：从命令行更新时，我收到错误消息

[ERROR] Failed to execute goal org.liquibase:liquibase-plugin:1.9.5.0:update (de
fault-cli) on project backend-persistence: Error setting up or running Liquibase
: liquibase.exception.JDBCException: Error executing SQL CREATE TABLE databasech
angeloglock (ID INT NOT NULL, LOCKED BOOLEAN NOT NULL, LOCKGRANTED TIMESTAMP WIT
H TIME ZONE, LOCKEDBY VARCHAR(255), CONSTRAINT PK_DATABASECHANGELOGLOCK PRIMARY
KEY (ID)): FEHLER: Relation ╗databasechangeloglock½ existiert bereits -> [Help 1
]

简单地删除db-table没有帮助，看起来liquibase正在创建它两次，如日志文件建议的那样：

...
CREATE TABLE databasechangeloglock (ID INT NOT NULL, LOCKED BOOLEAN NOT NULL, LOCKGRANTED TIMESTAMP WITH TIME ZONE, LOCKEDBY VARCHAR(255), CONSTRAINT PK_DATABASECHANGELOGLOCK PRIMARY KEY (ID))
COMMIT
BEGIN
INSERT INTO databasechangeloglock (ID, LOCKED) VALUES (1, false)
COMMIT
BEGIN
LECT NULL AS TABLE_CAT, n.nspname AS TABLE_SCHEM, c.relname AS TABLE_NAME,  CASE n.nspname 

....
CREATE TABLE databasechangeloglock (ID INT NOT NULL, LOCKED BOOLEAN NOT NULL, LOCKGRANTED TIMESTAMP WITH TIME ZONE, LOCKEDBY VARCHAR(255), CONSTRAINT PK_DATABASECHANGELOGLOCK PRIMARY KEY (ID))
FEHLER:  Relation »databasechangeloglock« existiert bereits (already exists)

任何想法如何解决这个问题？

提前致谢，

您的postgres数据库中可能有多个架构。要解决您的问题，请在公共架构中移动所有数据。
