未从条件步骤触发下游作业

Question

我有一个工作，同时执行将获得液基数据库锁。如果出现错误，作业将退出而不释放锁。因此，我需要在失败时触发下一个作业，以便它解锁数据库，并且使用数据库的其他作业不会因为这个锁而抛出错误。

......
[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)
...........

错误将类似于上面的内容。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"}

在执行时，日志如下：

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

]

您可以帮助标签和表达式部分如何配置它吗？提前谢谢。

问题是表达式和标签不匹配。Exp：.MATCH。标签：${BUILD_LOG_REGEX，regex=“无法获取更改日志锁”，linesBefore=0，linesAfter=0，maxMatches=1，showTruncatedLines=false，escapeHtml=true，substText="MATCH"，addNewline=false}我们必须在构建日志中查找“无法获取更改日志锁”，然后执行操作。请注意，label中的表达式是使用java表达式lang推导出来的。subsText和Exp应该匹配，这意味着包含文本“and‘t of change log lock”的整行将由" match“关键字填充。添加addNewline是因为在日志中添加了新行。
