Ian Young updated MJAVADOC-517:
-------------------------------
Description:
Under Java 10 EA, the plugin generates the following exception:
{code:java}
Caused by: java.lang.NullPointerException
at org.apache.commons.lang3.SystemUtils.isJavaVersionAtLeast
(SystemUtils.java:1626)
at
org.apache.maven.plugins.javadoc.AbstractJavadocMojo.getJavadocExecutable
(AbstractJavadocMojo.java:3683)
at org.apache.maven.plugins.javadoc.AbstractJavadocMojo.executeReport
(AbstractJavadocMojo.java:2001)
at org.apache.maven.plugins.javadoc.JavadocJar.doExecute
(JavadocJar.java:190)
{code}
This seems to be down to the version string:
{code:java}
java version "10" 2018-03-20
Java(TM) SE Runtime Environment 18.3 (build 10+43)
Java HotSpot(TM) 64-Bit Server VM 18.3 (build 10+43, mixed mode)
{code}
{{commons-lang3}} version 3.5 can't deal with this, see
https://issues.apache.org/jira/browse/LANG-1365
Inserting an explicit dependency on {{commons-lang3}} version 3.7 for the
plugin works round the issue, and changing the dependency seems like the right
fix for the next release of this plugin.
