“错误：无法从 Maven 存储库检索数据”

同时从 search.maven.org 检索最新版本号。 编写了以下 php 代码，我将针对所有其他包进行修改。

<?php
    $url = "https://search.maven.org/solrsearch/select?q=a:angus-activation-project&rows=1&wt=json";
    $curl = curl_init();
    curl_setopt($curl, CURLOPT_URL, $url);
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
    $response = curl_exec($curl);
    curl_close($curl);

    if ($response === false) {
        echo "Error: Retrieving data from the Maven repository failed";
    } else {
        $data = json_decode($response);
    if ($data === null || !property_exists($data, 'response') || count($data->response->docs) == 0) {
        echo "Error: Failed to retrieve the latest version of the artifact from the Maven repository";
    } else {
        $latestVersion = $data->response->docs[0]->v;
        echo "Latest version is" . $latestVersion;
    }
    }
?>
