我不太确定该怎么做。我根据 Travis 文档按照 gradle 设置项目，它应该可以正常工作...这是我的 travis 配置文件
language: java
jdk:
- oraclejdk8
- oraclejdk7
- openjdk7
before_script:
- chmod a+x gradlew
sccript: ./gradlew build
如果我通过 IntelliJ IDEA 或以下方式在本地构建：
gradle buildchmod a+x gradlew && ./gradlew build
它运行完美。有什么提示吗？
任何路过我的问题的人都在我的 .gitignore 文件中。我无意中添加了这个条目：
gradle/
导致 gradle/wrapper/gradle-wrapper.jar 未包含在我的回购中。删除 .gitignore 文件中的此项并将更改提交到 repo 修复了问题。
其实不仅要有gradle/wrapper/gradle-wrapper.jar，还要有-x权限。因此，如果您已经提交了它，但它没有 -x，您应该执行以下操作：
chmod +x gradle/wrapper/gradle-wrapper.jargit add -f gradle/wrapper/gradle-wrapper.jar
参考：
如果您不想将 .jar 文件添加到您的存储库中，您可以在 travi-ci 上开始构建之前安装 wrapper：
install: gradle wrapper --gradle-version 4.2
language: java
jdk:
- oraclejdk8
gradle documentation and install commands in travis-ci doc.
中有关包装器的更多信息
在我的例子中，我在存储库中有 gradle-wrapper.jar，但它仍然给了我：
Error: Could not find or load main class org.gradle.wrapper.GradleWrapperMain
事实证明，由于我在 .gitattributes 中强制执行了 LF 行结尾，因此 gradle-wrapper.jar 文件在提交期间损坏了。
要修复它，请执行以下操作：
- 在
.gitattributes中添加以下行*.jar binary
- 删除 gradle 包装文件：
rm -rf gradle/ gradlew gradlew.bat
- 重新生成包装器：
gradle wrapper --gradle-version=5.1.1 --distribution-type=all
- 提交并推送 :)
以上回答无效的，可以试试
jdk: openjdk8 而不是 .travis 文件中的 oraceljdk8
您可以检查 oracle JDK 和 Open Jdk 之间的区别。这应该无关紧要，因为两者都获得了甲骨文的许可，一个来自开放的 GNU PL，但如果您想要特定的区别，您可以访问
-https://www.baeldung.com/oracle-jdk-vs-openjdk

我不太确定该怎么做。我根据 Travis 文档按照 gradle 设置项目，它应该可以正常工作...这是我的 travis 配置文件
language: java
jdk:
- oraclejdk8
- oraclejdk7
- openjdk7
before_script:
- chmod a+x gradlew
sccript: ./gradlew build
如果我通过 IntelliJ IDEA 或以下方式在本地构建：
gradle buildchmod a+x gradlew && ./gradlew build
它运行完美。有什么提示吗？
任何路过我的问题的人都在我的 .gitignore 文件中。我无意中添加了这个条目：
gradle/
导致 gradle/wrapper/gradle-wrapper.jar 未包含在我的回购中。删除 .gitignore 文件中的此项并将更改提交到 repo 修复了问题。
其实不仅要有gradle/wrapper/gradle-wrapper.jar，还要有-x权限。因此，如果您已经提交了它，但它没有 -x，您应该执行以下操作：
chmod +x gradle/wrapper/gradle-wrapper.jargit add -f gradle/wrapper/gradle-wrapper.jar
参考：
如果您不想将 .jar 文件添加到您的存储库中，您可以在 travi-ci 上开始构建之前安装 wrapper：
install: gradle wrapper --gradle-version 4.2
language: java
jdk:
- oraclejdk8
gradle documentation and install commands in travis-ci doc.
中有关包装器的更多信息在我的例子中，我在存储库中有 gradle-wrapper.jar，但它仍然给了我：
Error: Could not find or load main class org.gradle.wrapper.GradleWrapperMain
事实证明，由于我在 .gitattributes 中强制执行了 LF 行结尾，因此 gradle-wrapper.jar 文件在提交期间损坏了。
要修复它，请执行以下操作：
- 在
.gitattributes中添加以下行*.jar binary - 删除 gradle 包装文件：
rm -rf gradle/ gradlew gradlew.bat - 重新生成包装器：
gradle wrapper --gradle-version=5.1.1 --distribution-type=all - 提交并推送 :)
以上回答无效的，可以试试
jdk: openjdk8 而不是 .travis 文件中的 oraceljdk8
您可以检查 oracle JDK 和 Open Jdk 之间的区别。这应该无关紧要，因为两者都获得了甲骨文的许可，一个来自开放的 GNU PL，但如果您想要特定的区别，您可以访问 -https://www.baeldung.com/oracle-jdk-vs-openjdk
