我已经在Windows上通过sdkman安装了Spring Boot CLI。现在，我尝试使用以下命令安装Spring Cloud CLI：
spring install org.springframework.cloud:spring-cloud-cli:2.0.0.RELEASE
我在公司代理后面，并出现以下错误：
Installing into: C:\Users\user\.sdkman\candidates\springboot\current\bin\..\lib\ext
startup failed:

到目前为止，我已经尝试过：
设置环境变量的变体：$JAVA_OPTS，JAVA_TOOL_OPTIONS，JAVA_OPTIONS。
全部具有价值：
-Dhttp.proxyHost=localhost -Dhttp.proxyPort=8888 -Dhttps.proxyHost=localhost -Dhttps.proxyPort=8888 -Dhttps.proxySet=true -Dhttp.proxySet=true
我在localhost：8888的代理对于其他应用程序运行正常。
在settings.xml上添加了Maven ~/.m2，因为我在Spring Boot CLI文档中阅读了此内容。
我的settings.xml如下：
<proxies>
<proxy>
<id>http</id>
<active>true</active>
<protocol>http</protocol>
<username>proxyuser</username>
<password>proxypass</password>
<host>localhost</host>
<port>8888</port>
<nonProxyHosts></nonProxyHosts>
</proxy>
<proxy>
<id>https</id>
<active>true</active>
<protocol>https</protocol>
<username>proxyuser</username>
<password>proxypass</password>
<host>localhost</host>
<port>8888</port>
<nonProxyHosts></nonProxyHosts>
</proxy>
</proxies>
但是没有效果。
