Question

大家，我正在构建spring boot项目，它具有多个模块。当我尝试安装到Maven文件时。服务器显示错误为无法解决的导入POM：无法在子模块中找到org.springframework.cloud:spring-cloud-dependencies:pom：$ {spring-cloud.version}。

显示日志

The project xx.xx.xx.xxx:config:0.1 (D:\xx\xx\config\pom.xml) has 2 errors

Non-resolvable import POM: Failure to find org.springframework.cloud:spring-cloud-dependencies:pom:${spring-cloud.version} in https://repo.maven.apache.org/maven2 was cached in the local repository, resolution will not be reattempted until the update interval of central has elapsed or updates are forced @ xx.xx.xx.xxx:xxx-config:[unknown-version], D:\xx\xx\config\pom.xml, line 26, column 25 -> [Help 2]


'dependencies.dependency.version' for org.springframework.cloud:spring-cloud-config-server:jar is missing. @ xx.xx.xx.xxx:xxx-config:[unknown-version], D:\xx\xx\config\pom.xml, line 37, column 21

这是我的父pom.xml

Answer 1

void FirebaseCall::analyzeError(char* method, int status, const std::string& path_with_auth) { if (status != 200) { error_ = FirebaseError(status, std::string(method) + " " + path_with_auth + ": " + http_->errorToString(status)); } else { error_ = FirebaseError(); } }属性似乎没有在任何地方定义。看着您的父pom，它似乎已经以某种方式损坏。它包含以下内容：

boolean WiFiReturns() {
    if (WiFi.localIP() == IPAddress(0, 0, 0, 0))
        return 0;

    switch (WiFi.status()) {
        case WL_NO_SHIELD: return 0;
        case WL_IDLE_STATUS: return 0;
        case WL_NO_SSID_AVAIL: return 0;
        case WL_SCAN_COMPLETED: return 1;
        case WL_CONNECTED: return 1;
        case WL_CONNECT_FAILED: return 0;
        case WL_CONNECTION_LOST: return 0;
        case WL_DISCONNECTED: return 0;
        default: return 0;
    }
}

void firebasereconnect() {
    Serial.println("Trying to reconnect");
    Firebase.begin(firebaseURl, authCode);
}

void loop() {

    if (!WiFiReturns()) { 
        WiFi.isConnected();
        digitalWrite(WIFILED, HIGH);
        firebasereconnect();
    } else { 
        digitalWrite(WIFILED, LOW);
    }
}

将其替换为以下内容可以解决您的问题：

spring-cloud.version

不可解析的导入POM：无法找到org.springframework.cloud:spring-cloud-dependencies:pom:${spring-cloud.version}
