VoltDB 9.0 真的支持 Java 11 吗？

Question

我目前只需要交叉编译几个针对 Java 8 的 JAR（在我的 Java 11 应用程序中），因为 VoltDB 仅支持在高达 8.4.x 的 DDL 期间加载 Java 8 JAR。理想情况下，我只想使用 Java 11，因为 Java 8 在商业上不再受支持。

查看 voltDB 9.0 的发行说明后，我看到了支持 Java 11 的项目符号行。首先，我尝试了 voltdb 站点的社区版版本，它不会加载我用 Java 11 编译的 JAR。所以我去了github并克隆了标记版本“voltdb-9.0”。我尝试使用 Java 11.0.3 构建“ant”。它失败并出现以下跟踪：

VoltDB 网站上只有旧版本的旧构建说明。有人可以帮我把它编译成 Java 11 吗？

VoltDB v9.0 将在 Java 11 上运行，但如果您是从源代码编译它，暂时您仍然需要使用 Java 8 进行编译。披露：我在 VoltDB 工作。
