Missing dependency to xalan-serializer?

[Nebelmann]

Hello everyone,

I started playing with DocBook today and tried to transform my XML file into a PDF using docbkx-maven-plugin 2.0.14. I have a problem when I run a maven build:

Caused by: java.lang.NoClassDefFoundError: org/apache/xml/serializer/TreeWalker

at org.apache.xalan.processor.TransformerFactoryImpl.newTransformer(TransformerFactoryImpl.java:821)

I googled this class and it seems that it's not contained in the xalan artifact but in the xalan-serializer artifact. Adding an extra dependency to the plugin works:

            <plugin>

                <groupId>com.agilejava.docbkx</groupId>

                <artifactId>docbkx-maven-plugin</artifactId>

                <version>2.0.14</version>

                <executions>

                    <execution>

                        <goals>

                            <goal>generate-pdf</goal>

                        </goals>

                        <phase>pre-site</phase>

                        <configuration>

                            <includes>myfile.xml</includes>

                        </configuration>

                    </execution>

                </executions>

                <configuration>

                    <paperType>A4</paperType>

                    <foCustomization>src/docbkx/docbook-fo.xsl</foCustomization>

                </configuration>

                <dependencies>

                    <dependency>

                        <groupId>net.sf.docbook</groupId>

                        <artifactId>docbook-xml</artifactId>

                        <version>5.0-all</version>

                        <classifier>resources</classifier>

                        <type>zip</type>

                        <scope>runtime</scope>

                    </dependency>

                    <dependency>

                        <groupId>xalan</groupId>

                        <artifactId>xalan-serializer</artifactId>

                        <version>2.7.0</version>

                        <scope>runtime</scope>

                    </dependency>

                </dependencies>

            </plugin>

Has anyone faced the same problem? Is it something missing from the maven plugin?

Thanks for your help.

Hello,

We never had issues about that but I will add the dependency, that way the issue will go away in any case.

Thanks. Perhaps the dependency was already in your classpath thanks to another dependency?
