Java-無法在Eclipse的項目瀏覽器中使用log4j

Question

我將Eclipse版本更新為4.9.0
我的項目在Maven中使用了log4j庫。
但是Maven構建會引發錯誤，從而阻止Eclipse項目瀏覽器中的Maven依賴關系。

請教我如何解決此問題。
謝謝。

我在pom.xml中使用了以下代碼

我將Eclipse版本移至Neon 4.6.3。
所以我將顯示的塊解析為log4j。
但在下面引發錯誤：

我在下面的Maven中有設置

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>3.1</version>
    <configuration>
        <source>1.8</source>
