如何完全离线构建gradle个项目？

Question

环境： Linux + JDK 11 + Gradle 5.0 我有几个 gradle 项目必须在没有互联网连接的情况下从源构建/例如这个 git clone --depth 1 --branch 3.0.0 https://github.com/bobbylight/RSyntaxTextArea.git 首先我在线构建了这个项目然后复制 ~/.gradle 到 $PROJECT_DIR/grdl ，接下来我想测试这个版本。我执行 gradle --stop ，清除整个 ~/.gradle 目录然后关闭互联网和运行以下脚本：

cp -r ./grdl/* ~/.gradle
cd RSyntaxTextArea
gradle --offline clean build

在我将这些文件移动到另一台 Linux+JDK11+Gradle 5.0 离线机器之前，一切都很好。当我运行相同的脚本时，出现以下错误：

./build.sh
Picked up _JAVA_OPTIONS: -Dawt.useSystemAAFontSettings=on -Dswing.aatext=true
Starting a Gradle Daemon, 1 incompatible Daemon could not be reused, use --status for details

FAILURE: Build failed with an exception.

五个 gradle 项目中有四个有类似问题。令人惊讶的是，一台机器在两台机器上都正常脱机，这台机器 - git clone --depth 1 --branch 0.27 https://github.com/JFormDesigner/FlatLaf.git 。我认为我没有正确理解 gradle 缓存。你能帮我在没有互联网的情况下构建 gradle 个项目吗？它可以是 Gradle 的任何版本，但我绑定到 Linux + JDK 11.

Answer 1

我认为您遇到了这个问题：https://github.com/gradle/gradle/issues/1338

也就是说，缓存项不可重定位。复制整个 ~/.gradle 文件夹可能还不够，尤其是当 ~ 解析到与原始计算机不同的路径（即不同的用户）时。完整路径需要完全相同（Gradle 5.0）。

然而，该问题表明版本 6.1 使缓存可重定位，因此您可能会更幸运地使用最新版本（7.2 是目前最新的版本）。

编辑：The release notes and these docs 确认从版本 6.1.1 开始可以跨部署复制缓存。

Answer 2

对我有用的一个解决方案是复制 $'username'/.gradle/caches/modules-2/files-2.1 文件夹

这包含 gradle 已缓存并可以重复使用的所有库。我认为这对于 gradle versons < gradle 6.1.

是不可能的

复制 files-2.1 文件夹后，您可以将 gradle 项目与打开 intellij/eclipse 的离线模式同步。

如果还是不行，复制整个caches文件夹。
