使用Bazel构建ONOS时遇报错问题求助

问题背景 #

• 遵循ONOS项目官方构建指南安装最新版Bazel后，系统提示需使用特定版本Bazel 6.0.0-pre.20220421.3，但通过apt无法找到该包
• 安装Bazel 6.0.0后无版本冲突提示，执行bazel-6.0.0 build onos时出现报错

报错详情 #

疑问补充 #

ONOS项目GitHub仓库无Issue板块，原谷歌群组已废弃，不清楚该通过什么渠道反馈项目问题？

验证可行的解决方案 #

使用Bazelisk自动适配并下载ONOS所需的Bazel版本，执行以下命令即可完成构建：

wget https://github.com/bazelbuild/bazelisk/releases/download/v1.18.0/bazelisk-linux-amd64
chmod +x bazelisk-linux-amd64
sudo mv bazelisk-linux-amd64 /usr/local/bin/bazel
cd path/to/onos
bazel build onos

构建成功输出：
