用Gradle進行Travis CI + Coverity掃描

Question

我已經成功設置了一個使用Travis CI進行構建和測試的項目。 現在，我正在嘗試添加Coverity Scan。

我創建了一個名為coverity_scan的分支，並將其設置為用於coverity構建。 將提交推送到該分支后，我可以在Travis CI構建控制台中看到Coverity工具開始執行其工作：

Coverity Scan analysis selected for branch coverity_scan.
Coverity Scan analysis authorized per quota.

...

Travis構建成功，在Coverity build-log.txt文件中，我看到以下內容：

2016-10-06T21:02:39.132946Z|cov-build|2665|info|>

但是，完成此操作后，我在Project Coverity儀表板中看不到任何已提交的構建或更改。 項目狀態保持為pending 。

我已按照本指南進行操作， .travis.yml如下所示設置了.travis.yml文件：

language: java
jdk:
  - oraclejdk8
before_script:
  - cd server
  - chmod +x gradlew
script:
  # Run tests when not on coverity branch.
  - if [ ${COVERITY_SCAN_BRANCH} != 1 ]; then
      ./gradlew check;
    fi
cache:
  directories:
  - ~/.gradle
after_success:
  # Upload coveralls when not on coverity branch.
  - if [ ${COVERITY_SCAN_BRANCH} != 1 ]; then
      ./gradlew cobertura coveralls;
    else
      cat cov-int/build-log.txt;
    fi
notifications:
  email:
    on_success: change
env:
  matrix:
    - TERM=dumb
  global:
    # COVERITY_SCAN_TOKEN
    - secure: "<TOKEN>"
before_install:
  - echo -n | openssl s_client -connect scan.coverity.com:443 | sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p' | sudo tee -a /etc/ssl/certs/ca-
addons:
  coverity_scan:
    project:
      name: "Edvinas01/chat-rooms"
      description: "Build submitted via Travis CI"
    notification_email: "<EMAIL>"
    build_command_prepend: "./gradlew clean"
    build_command: "./gradlew build"
branch_pattern: coverity_scan

我是否必須指定一些其他配置才能發布Coverity版本？

Answer 1

花了一些時間，並使用Java和覆蓋率分析工具創建了虛擬機。 拉動我的項目並運行該工具后，我在日志中注意到了這一點：

[WARNING] No files were emitted. This may be due to a problem with your configuration
or because no files were actually compiled by your build command.

經過一番擺弄並查看了其他項目之后，我發現這是由於Gradle版本引起的。 我的項目使用3.0所以我降級到2.14.1 ，它似乎終於可以正常工作了。

Answer 2

對於有價值的東西，只要確保不使用守護程序（只要可以在命令行上指定--no-daemon就可以在任何Gradle版本中使用Coverity都沒有問題。

就是說，還有許多其他容易錯過的陷阱，導致不很明顯的錯誤消息。

有關有用的背景，請參見Caleb的答案：
