Question

当我清理项目并干净运行时，一切正常。然后，当我尝试以build ..身份运行并将目标设置为package时，出现此错误：

<?php

 $xml = file_get_contents('note.xml');
 $dom = new DOMDocument();
 $dom->loadXML($xml);
 $xpath = new domXpath($dom);

 foreach ($xpath->query('//standard[header="MECHANICAL"]/description') as $mechdescription){
 $mecharray[] = $mechdescription->nodeValue ;
}
 foreach ($mecharray as $mechanicaldescription){
 echo $mechanicaldescription;
}

?>

大多数行上的multicatch看起来像这样，但是当我运行该应用程序时，该应用程序运行正常。

我不确定source 1.5意味着什么，我已经在google上搜索了如何在软件包构建中更改Maven源代码，但是找不到任何东西。任何帮助表示赞赏。

如果尚未在（super）pom.xml中明确包含它，请尝试直接配置该maven-compiler-plugin。添加以下内容：

<build>
    [...]
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-compiler-plugin</artifactId>
        <version>3.8.0</version>
        <configuration>
          <source>1.8</source>
          <target>1.8</target>
        </configuration>
      </plugin>
    </plugins>
    [...]
  </build>

由于来源1.5，无法建立套件目标
