Travis CI Spring Boot 错误（Gradle 错误）

Question

我在运行 Travis Ci 时遇到问题。我的 Spring Boot 应用程序出现以下错误。

.travis.yml文件

language: java
sudo: false
script: mvn clean verify

告诉我你需要哪些文件。

Answer 1

您似乎忘记签入 gradle/wrapper 中的文件。它应该有两个文件gradle-wrapper.jar 和gradle-wrapper.properties。

Answer 2

好的，所以问题是我的 Spring-boot 应用程序有 Maven 和 Gradle 文件。我相信，当我尝试不同的东西时，我生成了 Gradew 文件，因此 Travis CI 正在寻找 Gradle。

解决方案是删除所有 gradle 文件并重新运行 travis。我已经更新了我的 travis.yml 如下

jdk:
    - oraclejdk8

# would just use default install/script but the ./mvnw script errors on travis
# obviously this only works for maven builds right now...
install:
    - mvn install -DskipTests=true -Dmaven.javadoc.skip=true -B -V
    - mvn cobertura:cobertura

script:
    - mvn test

dist: trusty

after_success:
  - bash <(curl -s https://codecov.io/bash) -t
