我的Java版本:

java 9.0.4

Java(TM)SE运行时环境(构建9.0.4+11)

Java HotSpot(TM)64位服务器虚拟机(构建9.0.4+11,混合模式)

我的Maven版本:

Apache Maven 3.5.3(3383C37E1F9E9B3BC3DF505C29C8AFF9F295297;2018-02-24T22:49:05+03:00)

Java版本:9.0.4,供应商:Oracle公司

Java home:/Library/Java/JavaVirtualMachines/jdk-9.0.4.jdk/Contents/home

默认区域设置:en_TR,平台编码:UTF-8

操作系统名称:“mac OS x”,版本:“10.14.1”,拱门:“x86_64”,系列:“mac”


如果有人有任何信息或建议,我正在等待。

只需深入了解一下代码。您确定他们的构建脚本支持Java 9吗

请看您有问题的行:。请参阅
ToolProvider.getSystemToolClassLoader()
。现在让我们看一下Java 9:

已弃用。此方法将在Java SE的未来版本中删除。使用或机制定位系统工具以及用户安装的工具。 返回可用于加载系统工具的类加载器,如果未提供此类特殊加载器,则返回null

实施要求:

此实现始终返回null

看到了吗它总是返回
null

但是,Java 8中的一些东西:

返回此平台提供的工具的类加载器。这不包括用户安装的工具。使用服务提供程序机制查找用户安装的工具


因此,脚本在
null
对象上调用
getURLs
,显然抛出了一个NPE。它可能需要修复

谢谢你回来。那么,如何修复它呢?使用
java8
就足够了吗?试试吧。根据这里的答案,我将java版本从9降级到8,然后重新构建,我的问题就解决了,谢谢你的帮助。
