java - Spring Cloud DataFlow 组合任务未启动

Question

我正在尝试运行 SCDF 组合任务。我创建的任何组合任务都会执行相同的操作:执行 SQL 脚本:

Executing SQL script from class path resource [org/springframework/cloud/task/schema-h2.sql]`

此时执行暂停。在 SCDF 仪表板的 Executions 选项卡中，在 Start time 和 End time 处，我看到 N/A。

我正在使用 Spring Cloud DataFlow 1.2.3.RELEASE 和组合任务运行器 1.0.0.RELEASE。

这是日志的输出:

在服务器日志中，我看到许多不同的字符随着时间的推移而变化，例如:"[0x0][0x0][0x8][0x8][0x0][0xfa]CaJ[\r]3[0x99][0xd4]}[0x3][0x0][0x0][0x87][0x6] [0x0][0x0]3[0x0][0x0][0x0][0x0][0x0][0x0][0x0][0x0][0x0][0x0][0x0][0xa4][0x81] c[\n ]"

抱歉格式化，无法正确格式化输出

Answer 1

已解决。问题在于 Compated Task Runner 和 SCDF 中的 h2 版本不兼容。
