Description

As I am not expert for maven, I'm a bit lost here. We have projects which fail with the following error

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-site-plugin:3.7:site (default-cli) on project xxxx: Execution default-cli of goal org.apache.maven.plugins:maven-site-plugin:3.7:site failed: Invalid byte tag in constant pool: 18 -> [Help 1]

when executing this command

mvn site:site site-deploy -e -U

This occurs since we switched to java 8 and to my understanding it is somehow related to Java 8 and BCEL. However the message in the bug report is not exactly the same so I am not sure how or what do I have to configure to overcome the problem.

Here the essential info on how we have configured the site-plugin in the parent pom:

<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-site-plugin</artifactId>
<version>3.6</version>
<configuration>
    <locales>en</locales>
</configuration>
<dependencies>
    <dependency>
        <groupId>org.apache.maven.wagon</groupId>
        <artifactId>wagon-webdav-jackrabbit</artifactId>
        <version>${wagon.webdav.version}</version>
    </dependency>
</dependencies>
