JHipster gulp build未生成用于生产的app.js

我的应用程序在开发中运行良好。运行生产构建时，build/lib/www/app文件夹中缺少app.js。有人能提供一些关于如何追踪我的构建出了什么问题的见解吗

谢谢

更新： 我浏览了所有的gulpfile文件，试图了解发生了什么，最后找到了在assets:prod任务末尾调用的build函数。在该函数中，我替换了行中的templates变量

.pipe（gulpIf（'**/app.js'，页脚（模板）））

使用测试字符串，它可以工作。所以现在我要找出是哪个模板导致了这个问题。多痛苦啊。有没有办法让gulp向您提供更多的信息，例如错误发生地附近的一些字符

如果我单独运行gulp构建，我会得到：

每次尝试一个模板几个小时后，我终于发现问题在于模板中有一个拼写错误，模板中有一个$而不是&dollar；。这在构建函数中的JS相关子任务中引发了模糊错误。

如果打开gulpfile.JS，则有一个名为“html”的gulp任务。 如果您通过键入“gulp html”从终端运行此任务，它将在'target/tmp'文件夹中生成名为'templates.js'的文件。 此文件有多行$templateCache.put。 其中一行可能导致错误。 在产品配置文件中运行应用程序，并保持服务器运行

删除templates.js中几乎所有的$templateCache.put行（主页行除外），然后运行'gulpbuild'。 现在硬引用浏览器，检查您是否能够看到主页。 如果主页和其他行没有导致错误，您将看到主页

现在，将一些已删除的$templateCache.put行添加回templates.js，并再次运行“gulp build”

重复此过程，直到找到导致问题的线为止

一旦你发现这一行，检查它提到的html页面，并尝试删除该html文件中的所有注释

该html文件中的某些代码可能导致该问题

希望这有帮助。

我也有同样的问题。您是如何“一次尝试一个模板”的？gulp构建过程的一部分会生成一个角度模板缓存文件，该文件位于build/tmp/templates.js的项目根目录中。如果我没记错的话，这是在gulpfile.js中的“html”任务中完成的。您可以尝试构建一次，以便生成templates.js，然后注释掉构建过程的这一部分，这样文件就不会重新生成。然后在templates.js中，注释掉除第一行之外的所有$templateCache.put行，然后重新运行构建。如果成功，则取消对下一行的注释并再次构建，依此类推，直到找到导致构建失败的模板。哇！我在jhipster使用旧angularjs生成的应用程序中遇到了这个问题，问题是我使用“let”定义了一个变量。虽然它在开发过程中起作用——运行mvn和gulp，但一旦我

mvn-Pprod包

并部署到服务器上，它就不起作用了。一旦我将“let”变量声明替换为“var”，它就可以顺利运行了。
