Gitlab CI和gradle:如何在目录子文件夹中为项目运行gradlew构建

Question

我有一个存储库，我想在其中稍微分离一下源代码和文档。所以我的目录结构是这样的：

/
- .gitlab-ci.yml
- readme.md
+ doc/
- doc_files.txt
+ src/
+ server/
- gradlew
- source_code.java

因此，从回购的根源来看，我需要执行./src/server/gradlew build来构建项目。

现在我需要通过Gitlab CI触发gradle构建，也就是说，我会准确地执行所述命令。这就是我对gitlab-ci.yml:的设想

stages:
- build
server_build:
stage: build
image: gradle:7.5.1-jdk18-alpine
script:
- './gradlew build'

不管怎样，gradlew似乎不喜欢从任何其他目录执行，并失败如下：

> ./src/server/gradlew build
FAILURE: Build failed with an exception.
* What went wrong:
Directory '/home/user/git/project' does not contain a Gradle build.
A Gradle build should contain a 'settings.gradle' or 'settings.gradle.kts' file in its root directory. It may also contain a 'build.gradle' or 'build.gradle.kts' file.
//...
BUILD FAILED in 668ms

因此，我尝试用-p设置目录和/或用-b直接指向src/server/中的settings.gradle-无论如何，我会得到以下错误：

> ./src/server/gradlew -b settings.gradle -p src/server/ build
FAILURE: Build failed with an exception.
* What went wrong:
A problem occurred configuring root project 'server'.
> Could not open proj generic class cache for build file '/home/user/git/project/src/server/settings.gradle' (/home/user/.gradle/caches/7.5.1/scripts/qpzgz2vuqu1er7i9j90pmbyq).
> BUG! exception in phase 'semantic analysis' in source unit '_BuildScript_' Unsupported class file major version 63
// ...
BUILD FAILED in 667ms

而且，很明显，Gitlab CI失败了。因此，在.gitlab-ci.yml:中执行gradlew之前，我尝试将Gitlab CI的cd告知目录/src/server/

cd src/server && ./gradlew build

无论如何，这也不起作用，并且像这样失败(Gitlab CI中运行者的工作输出(：

// ...
$ cd src/server && ./gradlew build
Error: Could not find or load main class org.gradle.wrapper.GradleWrapperMain
Caused by: java.lang.ClassNotFoundException: org.gradle.wrapper.GradleWrapperMain
Cleaning up project directory and file based variables
ERROR: Job failed: exit code 1

在现有目录结构的情况下，我如何告诉Gitlab CI从存储库的根目录使用gradlew构建？

Answer 1

是否可以在.gitlab-ci.yml文件的before_script中导出GRADLE_USER_HOME。

before_script:
- export GRADLE_USER_HOME=`pwd`/.gradle

您可以在获取参考配置https://gist.github.com/daicham/5ac8461b8b49385244aa0977638c3420#file-gitlab ci yml

Answer 2

所以，我实际上是通过偶然发现解决方案来解决的。为了切入正题，我不得不重新添加文件gradle/wrapper/gradle-wrapper.jar，由于.gitignore，该文件没有上传。

总而言之，gitlab-ci.yml看起来是这样的：

stages:
- build
server_build:
stage: build
image: gradle:7.5.1-jdk18-alpine
script:
- cd src/server
- ./gradlew build

gitlab-ci.yml位于存储库的根目录中，整个Java/Spring Boot项目位于/src/server/中。这包括gradle.build、gradlew等等(特别是：从Spring Initializer中获得的所有内容https://start.spring.io/)。

因此，毕竟不需要任何路径配置。

您应该尝试在根目录中设置setting.gradle文件，并在src/server目录中设置build.gradle。使用-p应该可以正常工作。
