java - protoc 没有完全退出并且缺少： ---------- 1) com.google.protobuf:protoc:exe:${os.detected.classifier}:3.6.1

Question

我正在尝试构建 Maven，每次我eclipse使用maven updateget

Missing: ---------- 1) 
com.google.protobuf:protoc:exe:${os.detected.classifier}:3.6.1 error. 

从command line我得到以下错误。

[ERROR] Failed to execute goal org.xolstice.maven.plugins:protobuf-maven- 
plugin:0.5.1:compile (default) on project ivf-sample: protoc did not exit 
cleanly. Review output for more information. -> [Help 1]

有关如何解决此错误的任何建议专家？
