Question

我有一份工作，执行时会获得liquibase db lock。如果出现问题，则在不释放锁定的情况下退出作业。所以我需要在失败时触发下一个作业，以便它解锁数据库，使用数据库的其他作业不会因为这个锁而引发错误。

......
[ERROR]: Unexpected error running Liquibase: Could not acquire change log lock.  Currently locked by srvcldpcld262 since 4/28/17 8:40 AM
[ERROR]: SEVERE 4/28/17 10:48 AM: liquibase: Could not acquire change log lock.  Currently locked by srvcldpcld262 since 4/28/17 8:40 AM
[ERROR]: liquibase.exception.LockException: Could not acquire change log lock.  Currently locked by srvcldpcld262 since 4/28/17 8:40 AM

[ERROR]:    at liquibase.Liquibase.update(Liquibase.java:174)
[ERROR]:    at liquibase.integration.commandline.Main.doMigration(Main.java:997)
...........

错误将如上所述。现在我已经配置了一个条件步骤，它将运行正则表达式匹配，如下所示：

Expression: ^.*\s.*Could not acquire change log lock.*\s\[.*\s*
Label: ${BUILD_LOG_REGEX,regex="Could\snot\sacquire\schange\slog\slock"}

执行时，日志如下：

Regular expression run condition: Expression=[Could\snot\sacquire\schange\slog\slock], Label=[[...truncated 1841 lines...]

您能否请求标签和表达部分如何配置？提前谢谢。

问题是表达式和标签不匹配。 Exp：。 MATCH。 标签：$ {BUILD_LOG_REGEX，正则表达式=＆＃34;无法获取更改日志锁定＆＃34;，linesBefore = 0，linesAfter = 0，maxMatches = 1，showTruncatedLines = false，escapeHtml = true，substText =＆＃34; MATCH＆＃ 34;，addNewline = false} 我们不得不寻找＆＃34;无法获得更改日志锁定＆＃34;在构建日志中，然后执行操作。请注意标签内的表达式是使用java表达式lang推导出来的。 subsText和Exp应匹配意味着包含文本的整行＃34;无法获取更改日志锁定＆＃34;将被＃34; MATCH＆＃34;关键词。添加addNewline后，在日志中进行grepping后，添加了新行。

下游工作没有从条件步骤触发
