eclipse - Eclipse：在编辑器中打开没有问题时，如何从 Persistance.xml 中删除红色指示器？

Question

以下是我的persistance.xml，它没有显示任何错误：

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.2"
    xmlns="http://xmlns.jcp.org/xml/ns/persistence"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence http://xmlns.jcp.org/xml/ns/persistence/persistence_2_2.xsd">

    <persistence-unit name="IntegratorMasterdataDS"
        transaction-type="JTA">
        <provider>org.hibernate.ejb.HibernatePersistence</provider>
        <jta-data-source>java:/datasources/IasDS</jta-data-source>
        <properties>
            <property name="hibernate.archive.autodetection"
                value="class" />
            <property name="hibernate.show_sql" value="true" />
            <property name="hibernate.format_sql" value="true" />
        </properties>
    </persistence-unit>
</persistence>

以下是eclipse显示的红色指标：
