詹金斯：$ {BUILD_LOG，maxLines，escapeHtml}无法正常工作 [英] Jenkins: ${BUILD_LOG, maxLines, escapeHtml} not working

问题描述

我试图使用$ {BUILD_LOG，maxLines，escapeHtml}，如下所述：
如何从$ BUILD_LOG变量中获取最后20行？

不幸的是，它不适合我。

我得到这个错误：

Script1.groovy：114：期待任何事但''\ n'';
由用户MYUSERNAME制作

我在这行中的代码是： p>

  msg.setText（This build（+ build.getFullDisplayName（）
 +）包含以下任务：\\ \\ n \TASK \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\ \\ n $ {BUILD_LOG，maxLines = 9999，escapeHtml = false}）; 
  

---

如果我将以下内容展示出来， 。这就是为什么我的猜测是， BUILD_LOG 不再适用？
$ b

$ {BUILD_LOG，maxLines = 9999，escapeHtml = false}

---

编辑：
也许作为补充：我正在尝试使用PreSend groovy脚本来做到这一点。
由于我正在动态地构建电子邮件文本。
$ {BUILD_URL} 正常工作， $ {BUILD_LOG，maxLines = 9999，escapeHtml = false} doesn 't（对我来说）我正在寻找一个解决方案...
msg object是一个java MimeMessage。

感谢，

解决方案

该错误信息通常与未结束引号有关，注释以 / 而不是 // 等等开头。在你的代码中，我能看到的唯一的事情就是你的第三个行没有正确完成，即在\\\
\\\
\\\
链接到这个之后，你没有关闭双引号，而是开始一个新行（从而期望除''\ n''之外的任何内容。

尝试写出整行：

  msg.setText（This build（+ build.getFullDisplayName（）
 +）包含以下任务：\ n \TASK \\\\\\\\\\\\\\\\\\\\\\\' \\\
\\\
\\\
链接到此版本：$ {BUILD_URL} \ $ $ {BUILD_LOG，maxLines = 9999，escapeHtml = false}）; 
  

或者结束引号：

<$ p （+ build.getFullDisplayName（）
+）包含以下任务：\\\
\\\
TASK\t\t\ t IMPLEMENTER：\\\

+ taskList +\\\
\\\
\\\
链接到这个
+build：$ {BUILD_URL} \ $ $ {BUILD_LOG，maxLines = 9999， escapeHtml = false}）;

I am trying to use "${BUILD_LOG, maxLines, escapeHtml}" like discribed in: How can I take last 20 lines from the $BUILD_LOG variable?

Unfortunately it doesn't work for me.

I get this error:

Script1.groovy: 114: expecting anything but ''\n''; got it anyway @ line 114, column 301. arted by user MYUSERNAME

My code in this line is:

          msg.setText("This build (" + build.getFullDisplayName() 
          + " ) contains the following tasks:\n\nTASK\t\t\t  IMPLEMENTER:\n" 
          + taskList + "\n\n\nLink to this 
          build: ${BUILD_URL} \n ${BUILD_LOG, maxLines=9999, escapeHtml=false}" );

---

If I take this out the following, it works. Thats why my guess is, that "BUILD_LOG" is not working anymore?

${BUILD_LOG, maxLines=9999, escapeHtml=false}

---

EDIT: Maybe as addition: I am trying to do this withing the PreSend groovy script. Since I am building the Email text dynamically. ${BUILD_URL} works fine, ${BUILD_LOG, maxLines=9999, escapeHtml=false} doesn't (for me) i am looking for a solution for this... the msg object is a java MimeMessage.

Thanks, Daniel

解决方案

That error message is usually related to not closed quotes, comments started with / instead of //, etc. In your code the only thing I can see is that your third line is not finished properly, i.e., after "\n\n\nLink to this you are not closing double quotes and instead you are starting a new line (thereby the expecting anything but ''\n''.

Try to write the whole line:

msg.setText("This build (" + build.getFullDisplayName() 
          + " ) contains the following tasks:\n\nTASK\t\t\t  IMPLEMENTER:\n" 
          + taskList + "\n\n\nLink to this build: ${BUILD_URL} \n ${BUILD_LOG, maxLines=9999, escapeHtml=false}" );

or close the quotes instead:

msg.setText("This build (" + build.getFullDisplayName() 
          + " ) contains the following tasks:\n\nTASK\t\t\t  IMPLEMENTER:\n" 
          + taskList + "\n\n\nLink to this "
          + "build: ${BUILD_URL} \n ${BUILD_LOG, maxLines=9999, escapeHtml=false}" );
