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。0.01s$ java -Xmx32m -versionopenjdk version "11.0.2" 2019-01-15OpenJDK Runtime Environment 18.9 (build 11.0.2+9)OpenJDK 64-Bit Server VM 18.9 (build 11.0.2+9, mixed mode)$ javac -J-Xmx32m -versionjavac 11.0.23.37s$ ./gradlew assembleError: Could not find or load main class org.gradle.wrapper.GradleWrapperMainCaused by: java.lang.ClassNotFoundException: org.gradle.wrapper.GradleWrapperMainThe command "eval ./gradlew assemble " failed.

Answer 1

看起来您忘记签入 gradle/wrapper 中的文件。它应该有两个文件gradle-wrapper.jar和gradle-wrapper.properties.

Answer 2

好吧，问题是我的 Spring-boot 应用程序同时具有 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
