Answer 1

在执行推送时，顶部错误看起来像是在-p <path_to_war>参数中停止了。如果只是推送包含WAR文件的目录，Java buildpack将无法检测到它。

Answer 2

cf推送请求的输出中提供的提示是相关的。

 TIP: use 'cf logs jpu-henryhan --recent' for more information

运行该命令将拖尾在暂存过程中生成的日志文件，并让您查看可能引发的错误。通常，它可能是缺失的依赖或某种瞬态失败。

我刚刚使用＆＃34;部署到Bluemix＆＃34;成功部署了样本。按钮并通过cf命令行工具手动完成。除非您更改了代码，否则很可能是此错误是暂时性故障。

Answer 3

运行以下命令：

$ cf push jpu- -b https://github.com/cloudfoundry/java-buildpack --no-manifest --no-start -p PostgreSQLUpload.war

添加参数以设置buildpack＆＃34; -b https://github.com/cloudfoundry/java-buildpack＆＃34;
