Question

BadExitStatusException: Process exited with status 50 构建 bazel-0.5.0rc9 失败。终端输出错误如下

我收到向上错误，因为我在 CrosstoolConfigurationLoader.java 文件中添加了一些打印信息以进行调试。删除它可以修复它。

...
String selectedIdentifier = null;
String desiredCpu = cpuTransformer.apply(config.getCpu());
System.out.println("@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@");
System.out.println("desiredCpu="+desiredCpu);
System.out.println("@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@");
for (CrosstoolConfig.DefaultCpuToolchain selector : 
release.getDefaultToolchainList()) {
System.out.println("#########selector.getCpu()="+selector.getCpu());
if (selector.getCpu().equals(desiredCpu)) {
selectedIdentifier = selector.getToolchainIdentifier();
break;
}
...

错误详情见bazel#3017和bazel#3068，链接见上评论
