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DDL电压8.4.x以下加载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，我看到了对Java 11的支持。首先，我尝试了voltdb网站上的社区版本，该版本不会加载使用Java 11编译的JAR。因此，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“蚂蚁”。失败并显示以下跟踪：

VoltDB网站上只有较旧版本的旧版本说明。有人可以帮我将其编译为Java 11吗？

Answer 1

VoltDB v9.0将在Java 11上运行，但是如果您从源代码进行编译，暂时仍需要使用Java 8进行编译。披露：我在VoltDB工作。

VoltDB 9.0是否真正支持Java 11？
