我下载了elephantbird源代码,并试图通过运行“mvn包”进行构建,但出现以下错误:
[ERROR] Failed to execute goal com.github.igor-petruk.protobuf:protobuf-maven-plugin:0.4:run (default) on project elephant-bird-core: Unable to find 'protoc' -> [Help 1]
我使用的是mvnversion3.0.3,我在mac和ubuntu上试过,但是我得到了相同的错误。
编辑1:
感谢lorand的评论,我通过升级协议缓冲区解决了上述问题。我还安装了thrift 0.7.0,但现在在elephant pig构建期间又出现了一个编译失败:
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:2.3.2:testCompile (default-testCompile) on project elephant-bird-pig: Compilation failure: Compilation failure: [ERROR] /root/elephant-bird/pig/src/test/java/com/twitter/elephantbird/pig/util/TestThriftNameWritableConverter.java:[12,26] invalid inferred types for W; inferred type does not conform to declared bound(s)

确保您以前安装过
Protocol Buffers
(apt get install protobuf compiler)和Thrift
. 您还必须在elephant bird的pom.xml中设置thrift的位置。请参见:https://stackoverflow.com/a/12301954
