编译在Eclipse中有效，但在maven中无效

Question

The following piece of code using apache poi library results in compilation error when using maven with jdk 7. It works when using jdk 8.

    cell.getCellTypeEnum()

    [ERROR]   symbol:   method getCellTypeEnum()
    [ERROR]   location: variable cell of type org.apache.poi.ss.usermodel.Cell

The poi library used is 3.17 for both scenarios

    <dependency>
       <groupId>org.apache.poi</groupId>
       <artifactId>poi-ooxml</artifactId>
       <version>3.17</version>
    </dependency>

The maven dependency tree is as follows.

[INFO] com.iris.gst:txform:jar:1.0-SNAPSHOT
[INFO] +- org.apache.poi:poi-ooxml:jar:3.17:compile
[INFO] |  +- org.apache.poi:poi:jar:3.17:compile
[INFO] |  |  +- commons-codec:commons-codec:jar:1.10:compile
[INFO] |  |  \- org.apache.commons:commons-collections4:jar:4.1:compile
[INFO] |  +- org.apache.poi:poi-ooxml-schemas:jar:3.17:compile
[INFO] |  |  \- org.apache.xmlbeans:xmlbeans:jar:2.6.0:compile
[INFO] |  |     \- stax:stax-api:jar:1.0.1:compile
[INFO] |  \- com.github.virtuald:curvesapi:jar:1.04:compile
[INFO] \- junit:junit:jar:3.8.1:test

It also works perfectly in Eclipse. The eclipse project has been created using mvn eclipse:eclipse. Why does it not work with jdk 7 ?

Answer 1

The problem has been solved. In JDK 7 jre/lib/ext there is a poi-3.6.jar present. That was causing the problem.
