以前使用Apache包时，它们包含jar文件，我所要做的就是通过构建路径将它们导入。
在Apache POI（5.2.4-20230921）中，它现在使用Gradle来构建jar。
我尝试在Eclipse（2022-03）中构建POI，方法是导入-->Existing Gradle Project并选择根目录。当我这样做时，我得到以下内容：
提供的分阶段操作失败，并出现异常。配置项目“：poi”时出现问题。评估项目“：poi”时出现问题。无法计算任务"：poi：compileTestJava“属性”javaTester“的值。未找到与请求的规范匹配的工具链：{languageVersion=8，vendor=any，implementation=vendor-specific} for Windows on x86_64。没有本地安装的工具链匹配，并且尚未配置工具链下载存储库。poi-src-5.2.4- 20230921-5.2.4第0行Gradle错误标记
当我在命令行上尝试时，我得到了同样的东西。我在“https://docs.gradle.org/8.4/userguide/toolchains.html#sec:auto_detection“上查找了工具链信息，但没有任何帮助。运行--debug和--stacktrace给了我一堆对我来说意义不大的额外信息。
我没有从Apache更改build.gradle，但这里是工具链行：

java {
    toolchain {
        languageVersion = JavaLanguageVersion.of(jdkVersion)
        if (jdkVendor != '') vendor = JvmVendorSpec.matching(jdkVendor)
    }
    withJavadocJar()
    withSourcesJar()
}

字符串
我从来没有使用过Gradle之前，所以这可能是一些简单的东西.我使用的java 21.0.1 2023-10-17 LTS，这是今天下载并安装.它也没有与我以前的版本工作.
下载最新版本的Gradle并使用最新的Java和Apache包应该是一个非常无缝的过程。
为了解决第一条评论，我将gradle放入poi文件夹并运行gradle.bat。下面是命令和输出：

poi-src-5.2.4-20230921-5.2.4>gradle.bat
Configuration on demand is an incubating feature.

Deprecated Gradle features were used in this build, making it incompatible with Gradle 9.0.

You can use '--warning-mode all' to show the individual deprecation warnings and determine if they come from your own scripts or plugins.

For more on this, please refer to https://docs.gradle.org/8.4/userguide/command_line_interface.html#sec:command_line_warnings in the Gradle documentation.
