用于在Jenkins控制台日志中查找特定文本的Regex

Question

我正在编写Python脚本来过滤Jenkins控制台日志中的Jenkins作业，我想用正则表达式搜索特定的模式/文本。 以下是我要查找的文本：

somename.SomeTest.testSomeName()

以下段落或句子的一部分：

^{pr2}$

以上这些句子在控制台日志中出现了20多次。我想找到 然后得到方法名somename.SomeTest.testSomeName()。到目前为止，我已经尝试过了 缺少/不正确作为此正则表达式的一部分

下面是日志的小片段，我想从下面显示的每个日志中找出test method nameFailed to find the annotation....句子：

21:18:19    at org.apache.maven.surefire.testng.TestNGExecutor.run(TestNGExecutor.java:170)
21:18:19    at org.apache.maven.surefire.testng.TestNGXmlTestSuite.execute(TestNGXmlTestSuite.java:84)

21:18:26    at somename.client.test.utilities.platform.PlatformApiClient.sendRequest(PlatformApiClient.java:197)
21:18:26    at

上面只是一个小片段；想象一下上面的片段在日志中出现了20多次。在

Answer 1

我想你可以扫描每行的输出。试试这个regexp

.* ([^ ]+\(\)).*not deployed.*

示例如何使用Perl（regexp是相同的）与您的示例一起工作

^{pr2}$

Answer 2

说明

^.*?(\[Error\]).*?\.((?:[a-z]+\.){2}[a-z]+\(\))

此正则表达式将执行以下操作：

• 使用[error]查找所有行
• 捕获方法名，它是()前面的三个文本块
