Question

我是Travis CI的初学者，我正在尝试优化构建。我使用Apache Ivy作为依赖项管理器。默认情况下，Ivy将缓存放入~/.ivy2目录中。为了避免下载每个版本的依赖项，我在cache文件中设置了.travis.yml元素，如下所示：

cache:
   directories:
   - ~/.ivy2

我也尝试过：

cache:
   directories:
   - $HOME/.ivy2

没有运气。依赖关系不是从缓存中检索到的，而是每次都下载，如常春藤日志所说：

[ivy:retrieve] downloading https://repo1.maven.org/maven2/com/google/gwt/gwt-user/2.8.2/gwt-user-2.8.2.jar ...
[ivy:retrieve] ............................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................... (15915kB)
[ivy:retrieve]  [SUCCESSFUL ] com.google.gwt#gwt-user;2.8.2!gwt-user.jar (731ms)

我也尝试递归地列出ls -R ~/.ivy2中的Ivy缓存目录（before_script），但是没有任何输出。您能否告诉我如何使缓存有效？

Answer 1

-避免不必要的缓存更新

before_cache:
  # Cleanup the cached directories to avoid unnecessary cache updates
  - find $HOME/.ivy2/cache -name "ivydata-*.properties" -print -delete

-这些目录已缓存。

cache:
  directories:
    - $HOME/.ivy2/cache

在Travis CI上启用常春藤缓存持久性
