How to avoid java.lang.NoSuchMethodError: org.apache.poi.util.IOUtils.copy(Ljava/io/InputStream;Ljava/io/OutputStream;) in Apache POI

Question

I have a code for adding watermark to existing .doc file.

The following is the code I have tried so far

public static void main(String[] args)
{

    try
    {
        XWPFDocument xDoc = new XWPFDocument(new FileInputStream("test.doc"));
        XWPFHeaderFooterPolicy xFooter = new XWPFHeaderFooterPolicy(xDoc);
        xFooter.createWatermark("My Watermark");
    }
    catch(Exception e) {
        e.printStackTrace();
    }
}

The following is what I got

Exception in thread "main" java.lang.NoSuchMethodError: org.apache.poi.util.IOUtils.copy(Ljava/io/InputStream;Ljava/io/OutputStream;)V
at org.apache.poi.util.PackageHelper.open(PackageHelper.java:50)
at org.apache.poi.xwpf.usermodel.XWPFDocument.<init>(XWPFDocument.java:71)
at com.avi.Test.ReadDoc.main(Watermark.java:38)

I got this error today: "java.lang.NoSuchMethodError:org.apache.poi.util.POILogger.log(I[Ljava/lang/Object;)V]"

It looks different from your error, but quite similar. FYI, I'm using maven to manage jars. After some experiment, I found out the root case is the poi.jar and poi-ooxml.jar's version are not consistent.

This configuration will get an error:

    <dependency>
        <groupId>org.apache.poi</groupId>
        <artifactId>poi</artifactId>
        <version>3.12</version>
    </dependency>

    <dependency>
        <groupId>org.apache.poi</groupId>
        <artifactId>poi-ooxml</artifactId>
        <version>3.13</version>
    </dependency>

I changed the version of poi.jar from 3.12 to 3.13

    <dependency>
        <groupId>org.apache.poi</groupId>
        <artifactId>poi</artifactId>
        <version>3.13</version>
    </dependency>

    <dependency>
        <groupId>org.apache.poi</groupId>
        <artifactId>poi-ooxml</artifactId>
        <version>3.13</version>
    </dependency>

bingo, problem solved. I hope this will help someone who ran into this kind of Exception.
