Question

我通过以下命令克隆了Guava的存储库：

git clone https://code.google.com/p/guava-libraries/

因为我不完全熟悉Guava的结构，所以我尝试了以下命令：

cd guava-libraries
mvn test

不幸的是，我收到了以下错误（整个输出可查看here）。

[INFO] ------------------------------------------------------------------------

Missing:
----------
1) com.google.guava:guava:jar:sources:13.0-SNAPSHOT

  Try downloading the file manually from the project website.

  Then, install it using the command: 
      mvn install:install-file -DgroupId=com.google.guava -DartifactId=guava -Dversion=13.0-SNAPSHOT -Dclassifier=sources -Dpackaging=jar -Dfile=/path/to/file

  Alternatively, if you host your own repository you can deploy the file there: 
      mvn deploy:deploy-file -DgroupId=com.google.guava -DartifactId=guava -Dversion=13.0-SNAPSHOT -Dclassifier=sources -Dpackaging=jar -Dfile=/path/to/file -Durl=[url] -DrepositoryId=[id]

  Path to dependency: 
    1) com.google.guava:guava-gwt:jar:13.0-SNAPSHOT
    2) com.google.guava:guava:jar:sources:13.0-SNAPSHOT

----------
1 required artifact is missing.

for artifact: 
  com.google.guava:guava-gwt:jar:13.0-SNAPSHOT

from the specified remote repositories:
  central (http://repo1.maven.org/maven2),
  sonatype-nexus-snapshots (https://oss.sonatype.org/content/repositories/snapshots)

如何运行Guava的单元测试？

Answer 1

在完成安装到本地存储库之前，您无法运行mvn test。请第一次运行：

mvn clean install

然后您只能运行mvn test。 SNAPSHOT的库尚未在存储库中提供。

Answer 2

为什么在Maven Central提供候选版本时使用快照修订版？

<dependency>
    <groupId>com.google.guava</groupId>
    <artifactId>guava</artifactId>
    <version>13.0-rc2</version>
</dependency>
