Bug #888: Mvn build fails with Java 8
http://tools.lsc-project.org/issues/888
Author: Soisik Froger
Status: New
Priority: Normal
Assigned to:
Category: Packaging
Target version: 2.1.4
Problem in version: 2.1.3
Environment : Apache Maven 3.3.9, JDK version: 1.8.0_111
Command : mvn -opendj clean package
Here are some minor adaptations on the pom.xml so LSC can be built successfully
with java 8 without having to switch to JDK 7 or 6.
1. bc-jdk-version property missing,
Solution : simply adding a jdk18 profile based on jdk17 profile.
2. "'file' access is not allowed due to restriction set by the
accessExternalSchema property" during maven-jaxb2-plugin generate-sources phase
:
org.xml.sax.SAXParseException; systemId:
jar:file:/home/sfroger/.m2/repository/com/sun/xml/bind/jaxb-xjc/2.2.6/jaxb-xjc-2.2.6.jar!/com/sun/tools/xjc/reader/xmlschema/bindinfo/binding.xsd;
lineNumber: 52; columnNumber: 88; schema_reference: Failed to read schema
document 'xjc.xsd', because 'file' access is not allowed due to restriction set
by the accessExternalSchema property.
at
com.sun.org.apache.xerces.internal.util.ErrorHandlerWrapper.createSAXParseException(ErrorHandlerWrapper.java:203)
See https://java.net/jira/browse/MAVEN_JAXB2_PLUGIN-80. Solutions :
- Quick fix : Use the workaround provided in bug report : works.
=> I'd suggest we go for this solution for 2.1.4
- Long term fix : Upgrade maven-jaxb2-plugin from 0.8.0 to 0.9.0+ : works but
I'd like to further analyze for potential side effects, because generated
lsc.episode and WS API are differents when generated with newer plugins;
=> I will create a specific issue for libraries upgrade (target release is
2.2.0)
3. Javadoc generation fails when HTLM do not validate.
See
http://stackoverflow.com/questions/15886209/maven-is-not-working-in-java-8-when-javadoc-tags-are-incomplete
- Quick fix : These errors can be ignored by the plugin by adding a property to
jdk18 profile et passing it to the plugin during java doc generation
<javadoc.opts>-Xdoclint:none</javadoc.opts>
=> I'd suggest we go for this solution for 2.1.4
- Long term fix : Correct the errors and warnings in the javadoc commentaries
throughout source code
=> I will create a specific issue for this task (targeted release is 2.2.0).
Lots of classes will be impacted.
See attached patch.
Notes :
- Also tested with Apache Maven 3.0.2 & Java 1.6.
