Question

在构建java bazel项目时获取以下错误->

$ bazel build :all

如何解决bazel构建问题？我使用的是Bazel版本的4.0.0

Answer 1

设置bazel工具链并用以下内容更新.bazelrc文件解决了我的问题->

$ cat ~/.bazelrc
startup --server_javabase=/build/toolchain/lin64/jdk-1.8.0_201

startup --host_jvm_args=-Xms2G
startup --host_jvm_args=-Xmx2G

build --remote_http_cache=http://127.0.0.1:9090
build --remote_upload_local_results=true
build --remote_timeout=15
