maven无法在eclipse里build，但可以在eclipse外build

Question

pom.xml

            <plugin>
                <artifactId>maven-compiler-plugin</artifactId>
                <version>3.6.1</version>
                <configuration>
                    <source>1.8</source>
                    <target>1.8</target>
                    <fork>true</fork>
                    <encoding>UTF-8</encoding>
                    <executable>"%JAVA_HOME%\bin\javac.exe"</executable>
                </configuration>
            </plugin>

eclipse里报错如下：
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.6.1:compile (default-compile) on project fileuploader: Compilation failure -> [Help 1]
