Question

我是Liquibase的新手，我了解到diff和diffChangeLog这两种模式在相反的方向上使用目标数据库和基准（参考）数据库。

Using "diff" will show the difference going from 'base (reference)' -> 'target' which makes sense.
While "diffChangeLog" outputs the difference going from 'target' to 'base (reference)'.

我执行了Maven目标liquibase:diffChangeLog，但遇到以下错误

[ERROR] Could not find goal 'diffChangeLog' in plugin 
org.liquibase:liquibase-maven-plugin:3.5.1 among available goals dropAll, 
rollback, clearCheckSums, updateTestingRollback, changelogSync, updateSQL, 
migrateSQL, generateChangeLog, dbDoc, status, listLocks, changelogSyncSQL, 
releaseLocks, migrate, tag, diff, rollbackSQL, futureRollbackSQL, update, 
help -> [Help 1]

我做错了什么？我该如何以liquibase:diffChangeLog身份运行Maven？

Answer 1

diff（liquibase:diff）是用于查找数据库状态之间差异的maven goal。

diffChangeLog是command line的参数，用于使用Liquibase进行command line tool操作。没有称为liquibase:diffChangeLog

的目标

内部代码如下

    if ("diff".equalsIgnoreCase(this.command)) {
    CommandLineUtils.doDiff(createReferenceDatabaseFromCommandParams(this.commandParams, fileOpener), database, StringUtils.trimToNull(this.diffTypes), finalSchemaComparisons);
  }
  else if ("diffChangeLog".equalsIgnoreCase(this.command)) {
    CommandLineUtils.doDiffToChangeLog(this.changeLogFile, createReferenceDatabaseFromCommandParams(this.commandParams, fileOpener), database, diffOutputControl, StringUtils.trimToNull(this.diffTypes), finalSchemaComparisons);
  }

liquibase diff和diffChangeLog有什么区别？如何为diffChangeLog运行maven命令？
