由于Maven导致的错误，无法从代码构建和安装保险箱

我希望做一些OSS工作，以便在软件工程方面动手。我想为保险箱贡献一份力量。

问题面临:
我不能够建立保险箱的构建步骤:

git clone https://github.com/strongbox/strongbox
cd strongbox
mvn clean install

输出:
执行mvn clean install. cfg命令后我收到的输出是:

从这里的错误信息中我可以推断出，支持的JDK版本有问题，如下行-

[ERROR] Ubuntu 11.0.11+9-Ubuntu-0ubuntu2.20.04不是支持的JDK版本!

问题:

我应该做些什么来纠正这个问题?
,这是最好的(时间)的方式构建java软件?
如果我要使用IntelliJ IDEA，使用它更好吗?
错误信息还表明问题可能是由于maven插件本身。不确定,我将很感激如果有人指出正确的方向。

还有，如何在输出开始时去掉警告。

我的系统配置是:

OS: Ubuntu 20.04
Java版本:11.0.11(安装步骤如下)
Maven版本:3.6.3(从这里描述的步骤安装)

其他信息:

我有settings.xml文件在~/.m2/

Thanks in advance

回答您的问题:

你可以在github页面查看当前的保险箱要求:

需求

Java 1.8。X(我们目前不支持更高版本)

这就意味着你需要使用Java 1.8的某个版本。

我不太明白这个问题。你的意思是如果Maven构建Java软件或者是最好的方法吗?
那是个人意见的问题。如果你有机会使用Intelij IDEA，我建议你检查一下，自己决定。
错误信息被强制执行插件打印为:

提供了控制特定环境约束的目标，如Maven版本、JDK版本和OS系列，以及更多的内置规则和用户创建的规则。

意味着在这种情况下，强制执行器插件强制执行正确的Java版本，或者更具体地说，它不允许使用Java 11，因为项目打算用Java 1.8编译。

使用Java 1.8:)。这些警告指的是反射操作，这些操作在较新的Java版本中被认为是非法的，但在Java 1.8中是没问题的。
