问题描述
我想在 armhf 上的 chroot 环境中运行 gradle。
要设置 chroot，我使用：
#This will need ~5-10 minutes
sudo debootstrap --arch armhf sid armhf-chroot
sudo chroot armhf-chroot
#Now in the chroot environment run
mount -t proc /proc proc/
apt install openjdk-15-jdk gradle
现在，例如运行 gradle --version：
输出：
org.gradle.api.internal.classpath.UnkNownModuleException: Cannot locate JAR for module 'ant' in distribution directory '/usr/share/gradle'.
at org.gradle.api.internal.classpath.DefaultModuleRegistry.getExternalModule(DefaultModuleRegistry.java:78)
at org.gradle.api.internal.DefaultClasspathProvider.findClasspath(DefaultClasspathProvider.java:45)

at org.gradle.launcher.bootstrap.ProcessBootstrap.run(ProcessBootstrap.java:37)
at org.gradle.launcher.GradleMain.main(GradleMain.java:23)
在那之后，我尝试使用更新的版本（比如 6.8.3，而不是 apt 的 4.xy 版本）：
apt purge ant gradle
apt autoremove
apt install wget unzip
wget https://services.gradle.org/distributions/gradle-6.8.3-bin.zip
unzip gradle-6.8.3-bin.zip
cd gradle-6.8.3/bin
现在运行 ./gradle --version 失败并出现相同的错误：
org.gradle.api.internal.classpath.UnkNownModuleException: Cannot locate JAR for module 'ant' in distribution directory '/gradle-6.8.3'.
at org.gradle.api.internal.classpath.DefaultModuleRegistry.loadExternalModule(DefaultModuleRegistry.java:108)

at org.gradle.launcher.bootstrap.ProcessBootstrap.run(ProcessBootstrap.java:37)
at org.gradle.launcher.GradleMain.main(GradleMain.java:31)
我找到了 this 个帖子，但仍然失败：
export GRADLE_HOME=/gradle-6.8.3
export GRADLE_USER_HOME=/gradle-6.8.3
现在我的第三次尝试是使用 gradle 包装器，但这仍然失败：
cd /
apt install git
#Some sample project,the project itself is not that important
git clone https://github.com/jitpack/gradle-simple
cd gradle-simple
./gradlew
这会导致此错误：

在研究这个问题后，我发现了两个相关的帖子：this one 和 this。
但似乎所有这些问题都与 Java 15 无关，而更像是 Java 7-9。
我的机器：5.10.0-4-amd64 #1 SMP Debian 5.10.19-1 (2021-03-02) x86_64 GNU/Linux
