Travis和Coverity扫描-一切构建，但coverity似乎没有运行

Question

这是我非常简单的C++/CMake .travis.yml

env:
  global:
   # The next declaration is the encrypted COVERITY_SCAN_TOKEN, created
   #   via the "travis encrypt" command using the project repo's public key
   - secure: "<very long encrypted token>"

addons:
  coverity_scan:
    project:
      name: "tinverse/tsm"
    build_command_prepend: cmake .
    build_command: make
    branch_pattern: coverity_scan
  script:
    - echo -n | openssl s_client -CApath /etc/ssl/certs -connect scan.coverity.com:443 | sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p' | sudo tee -a /etc/ssl/certs/ca-

  apt:
    sources:
    - ubuntu-toolchain-r-test
    packages:
    - gcc-5
    - g++-5
    - clang

compiler:
  - gcc
  - clang

install:
# Use g++5.4 and not 4.6 (C++11 missing)
  - if [ "$CXX" = "g++" ]; then export CXX="g++-5" CC="gcc-5"; fi

一切都构建得很好。我没有看到coverity运行或上传任何东西。我使用未加密的令牌在travis中添加了一个'COVERITY_SCAN_TOKEN‘环境变量。构建日志在这里：https://travis-ci.org/tinverse/tsm/jobs/509506031。我得到了最后一个"The command“。/configure && make && make test”exited with 0.“来自travis-ci构建日志的消息，仅此而已！不知道我做错了什么。

更新:从构建日志：

depth=1 C = BE, O = GlobalSign nv-sa, CN = GlobalSign CloudSSL CA - SHA256 - G3
verify error:num=20:unable to get local issuer certificate
verify return:0
DONE

但是，在将CApath选项添加到.travil.yml中脚本的before_install部分中的openssl命令之后，我看到

echo -n | openssl s_client -CApath /etc/ssl/certs/ -connect scan.coverity.com:443 | sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p' | sudo tee -a /etc/ssl/certs/ca-certificates.crt
depth=2 C = BE, O = GlobalSign nv-sa, OU = Root CA, CN = GlobalSign Root CA
verify return:1
depth=1 C = BE, O = GlobalSign nv-sa, CN = GlobalSign CloudSSL CA - SHA256 - G3
verify return:1
depth=0 C = US, ST = Delaware, L = Dover, O = Incapsula Inc, CN = incapsula.com
verify return:1
DONE

那么，这里的非零返回是否意味着成功？尽管如此，看看travis-ci的构建日志，我认为coverity扫描没有运行。

Answer 1

我的分支名为feature/coverity_scan，我认为branch_pattern: coverity_scan会起作用。事实并非如此。在将我的分支重命名为coverity_scan之后，它起作用了。

此外，将dist: xenial添加到.travis.yml文件可以消除证书错误。
