Question

我有Ubuntu 18.04.1 LTS x86_64，我尝试使用Bazel version 0.17.2构建this存储库

Build target: bazel-out/k8-opt/bin/src/main/java/com/google/devtools/build/lib/bazel/BazelServer_deploy.jar
Build time: Fri Sep 21 10:31:42 2018 (1537525902)
Build timestamp: 1537525902
Build timestamp as int: 1537525902

启动这两个命令后：

bazel run //greeter_plugin:greeter_demo
bazel run //greeter_tensorboard -- --logdir=/tmp/greeter_demo

Bazel给我这个错误：

INFO: Analysed target //greeter_tensorboard:greeter_tensorboard (1 packages loaded).
INFO: Found 1 target...

我的OpenJDK版本是"1.8.0_181"

OpenJDK Runtime Environment (build 1.8.0_181-8u181-b13-0ubuntu0.18.04.1-b13)    
OpenJDK 64-Bit Server VM (build 25.181-b13, mixed mode)

有人可以帮我吗？谢谢！

您的JDK无关紧要：bazel嵌入了第三方的JDK（由Azul系统公司提供）。您可以使用bazel info进行验证。

现在，问题的确是@io_bazel_rules_closure/java/io/bazel/rules/closure/http使用了非常旧的Dagger版本，而Dagger不知道“ javax.annotation”。

在issue rules_closure/#275

中对此进行了跟踪
