我在构建 Tomcat .war 的 github CLIFF 存储库时遇到问题。
https://github.com/c4fcm/CLIFF
David-Laxers-MacBook-Pro:CLIFF davidlaxer$ java -version
java version "1.8.0_05"
Java(TM) SE Runtime Environment (build 1.8.0_05-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.5-b02, mixed mode)
David-Laxers-MacBook-Pro:CLIFF davidlaxer$ mvn -version
Apache Maven 3.2.1 (ea8b2b07643dbb1b84b6d16e1f08391b666bc1e9; 2014-02-14T09:37:52-08:00)
Maven home: /Users/davidlaxer/Downloads/apache-maven-3.2.1

The project builds (e.g. - mvn package) in the CLIFF parent:
E.g.
[INFO] Reactor Summary:

[INFO] CLIFF ............................................. SUCCESS [ 0.003 s]
[INFO] common ............................................ SUCCESS [ 2.854 s]

[INFO] cliff ............................................. SUCCESS [ 18.804 s]
[INFO] ------------------------------------------------------------------------
[INFO] BUILD SUCCESS
[INFO] ----------------------------------------------------------------
It gets a dependency error in the child:
e.g stanford-entity-extractor:

[INFO] BUILD FAILURE

我在这里没有看到 stanford-entity-extractor:jar:2.3.0 的 .jar:
http://mvnrepository.com/artifact/edu.stanford.nlp/stanford-corenlp

最佳答案
看起来 stanford-entity-extractor 和 common 是本地或公开不可用的子模块 jar。如果您尚未运行 mvn install，它们的 jar 尚未安装在您的本地存储库中，因此它们将无法解析。
关于Maven 依赖问题 : Could not resolve dependencies for project，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/32210233/
