java - 未能在项目 hapi-fhir-jpaserver-starter 上执行目标 org.apache.maven.plugins :maven-war-plugin:3. 2.3:war (default-war)

Question

因此，在 VPS Ubuntu 服务器上尝试使用 Maven 进行全新安装时出现此错误。
我已经安装了必要的元素来制作它，但仍然无济于事。

所以我从昨天开始尝试设置 iHRS 请我需要帮助

Answer 1

问题在于这条日志消息(见最后一行!)

Error assembling WAR: Problem creating war: Execution exception: Java heap space

之前 通过 mvn clean install 触发构建，在同一 shell/终端中发出以下命令:

export MAVEN_OPTS="-Xmx2048m -XX:MaxPermSize=128m"

它将允许 Maven 在构建阶段使用更多 RAM - 这里最多 2048 MB。如果它不起作用，您可以进一步增加此值以查看构建是否通过。请记住，您的机器/工作站需要这么多可用的物理 RAM。否则，构建显然会:再次失败。
