当我尝试单独部署时，我遇到了错误。

当我试图推进我的本地PCF时，我的误差低于此值。

（无论如何试图处理）

看起来你的一些JAR很糟糕。当您使用Maven或Gradle下载应用程序的依赖项时，可能会发生Maven / Gradle无法下载JAR但失败的JAR被缓存的情况。缓存的JAR始终用于前进，因为它是缓存。然后你会得到像你所看到的错误。

最简单的方法是进入缓存并删除列出的JAR的目录。 Maven缓存位于function changeColorConstructor(greenLimit, redLimit) { console.log('1. Green Limit in Constructor shell: ' + greenLimit); return function (metric) { var color; console.log('3. Green Limit in returned function: ' + greenLimit); if (metric >= greenLimit) { console.log('Green'); color = '#56C621'; // green } else if (metric < greenLimit && metric > redLimit) { console.log('Yellow'); color = '#F2E607'; // yellow } else if (metric <= redLimit) { console.log('Red'); color = '#C64C20'; // red } else { color = '#C0C0C0' } return color; }; } var indexColor = changeColorConstructor(5000, 10000); console.log('2. Returned function: ' + indexColor); console.log('4. Output from production function: ' + indexColor(5000));之下，gradle为~/.m2/repository。只需在这些文件夹下查找~/.gradle/caches（或任何JAR提供错误）并删除。然后重建您的应用并再次部署。
