问无法产生液化基变化量g

EN

我试图在命令提示符上执行命令：

liquibase --driver=com.mysql.jdbc.Driver --classpath=E:\mysqljar\mysql.jar --changeLogFile=E:\1.xml --url="jdbc:mysql://localhost:3306/abc" --username=root --password=root generateChangeLog

但是我发现了一个错误：

Liquibase更新失败:空结果集，预期一行严重24/9/13 6:29下午:液化基:空结果集，预期一行liquibase.statement.core.GetViewDefinitionStatement@53330681 :错误获取jdbc:mysql://localhost:3306/abc视图与liquibase.snapshot.jvm.JdbcDatabaseSnapshotGenerator.readView(JdbcDatabaseSnapshotGenerator.java:168) at liquibase.snapshot.jvm.JdbcDatabaseSnapshotGenerator.readViews(JdbcDatabaseSnapshotGenerator.java:304) at liquibase.snapshot.jvm.JdbcDatabaseSnapshotGenerator.createSnapshot(JdbcDatabaseSnapshotGenerator.java:241) at liquibase.snapshot.DatabaseSnapshotGeneratorFactory.createSnapshot(DatabaseSnapshotGeneratorFactory.java:69)在liquibase.integration.commandline.CommandLineUtils.doGenerateChangeLog(CommandLineUtils.java:145) at liquibase.integration.commandline.Main.doMigration(Main.java:760) at liquibase.integration.commandline.Main.main(Main.java:134)引起的liquibase.diff.Diff.compare(Diff.java:63)：liquibase.exception.DatabaseException:空结果集，预计一排在liquibase.util.JdbcUtils.requiredSingleResult(JdbcUtils.java:124)在liquibase.executor.jvm.JdbcExecutor.queryForObject(JdbcExecutor.java:159)在liquibase.executor.jvm.JdbcExecutor.queryForObject(JdbcExecutor.java:167)在liquibase.executor.jvm.JdbcExecutor.queryForObject(JdbcExecutor.java:163)在liquibase.database.AbstractDatabase.getViewDefinition(AbstractDatabase.java:748)在liquibase.snapshot.jvm.JdbcDatabaseSnapshotGenerator.readView(JdbcDatabaseSnapshotGenerator.java:166) .再来7个

有人能帮我解释一下吗？
