The class com.sun.xml.bind.v2.model.annotation.AnnotationReader was part of jaxb-impl 2.1.6, but has been removed in 2.1.7. Does anybody know why?
JAXB artifacts were restructured in 2.2.11 so a few classes were moved between jaxb-runtime and jaxb-core. AnnotationReader is not the only one. The main reason is (probably) the mavenisation which required rearranging a few classes due to dependency structure.
Unfortunately the old artifacts com.sun.xml.bind:* has a bit wrong dependency structure so if you just used jaxb-impl before you'd also need jaxb-core. If this was your problem you should move to the new org.glassfish.jaxb:* artifacts as they have the right structure. org.glassfish.jaxb:jaxb-core is a dependency of org.glassfish.jaxb:jaxb-runtime which replaces the old org.glassfish.jaxb:jaxb-impl.

The AnnotationReader is now part of jaxb-core.

I'm using Eclipse 4.5 with the Groovy-Eclipse 2.9.2/4.5 plugin which I thought was supposed to have the Groovy 2.5 compiler. However, it didn't have any picocli support so I added the groovy-cli-picocli-2.5.2-indy.jar to my classpath and was able to compile. However #2, when trying to run the script via Eclipse I get:
java.lang.ClassNotFoundException: picocli.CommandLine$ParameterException
It looks like groovy-cli-picocli-2.5.2-indy.jar does not have CommandLine class at all.
I would just throw jars at this from the fullblown picocli distribution but I'm under the impression they all have to somehow wrap nicely into Eclipse Groovy library via groovy.cli.picocli.CliBuilder.
Is my Groovy 2.5.2 missing this or am I somehow missing the boat on how it's supposed to work because picocli is not working for me in this configuration. Thanks!
You are correct: groovy-cli-picocli-2.5.2.jar (and groovy-cli-picocli-2.5.2-indy.jar) do not contain the picocli classes.
You need to add the picocli jar to the classpath.
If you use Maven, the groovy-all POM should include all dependencies.
(My original answer mentioned picocli classes that are shaded into the groovy-2.5.x.jar under the groovyjarjarpicocli package but these are intended for use internally by Groovy and not meant to be used by applications.)
I believe this problem not to be related to module exclusions in JDK 9 (as with java.se.ee), but rather with the fact that JDK 9 includes a newer version of org.w3c.dom.ls in the java.xml module that does not have the DocumentLS class.
The important bit of the stack trace is this:
Caused by: org.springframework.beans.factory.BeanDefinitionStoreException: Unexpected exception parsing XML document from class path resource [spring-test/test-container.xml]; nested exception is java.lang.NoClassDefFoundError: org/w3c/dom/ls/DocumentLS

Even if I include a runtime dependency with this class, like xerces:xerces 2.4.0, the JDK java.xml module is preferred (I guess).
I am using Gradle 4.1. Is there any way to restrict the scope of a
JDK provided module?
As you have correctly analyzed, the package org.w3c.dom.ls is present in the platform module java.xml. Any class on the class path that is in the same package will be ignored. That's called a split package and several fixes exist - the following two might help you.
Patch java.xml
You can add the classes of the Xerxes JAR to the java.xml module with --patch-module:
java --patch-module java.xml=xerxes-4.0.0.jar ...
I've never tried that with a JAR that contains some of the same classes. As I understand it, the JDK classes will then be replaced with the Xerxes classes, which means they better be a fully binary compatible replacement.
Upgrade java.xml
Another hope is to replace java.xml with the upgrade module path:
The upgrade module path (--upgrade-module-path) contains compiled definitions of modules intended to be used in place of upgradeable modules built-in to the environment (compile time and run time).
You face two problems:
the upgrade module path is supposed to be used only for upgradable modules (which java.xml is not), but I think I've read somewhere that that's not enforced (yet?) - didn't try it
the artifact you replace java.xml with needs to be fully binary compatible update - would that be the case for Xerxes?
From what I can tell, DocumentLS is from a 2002 draft of the W3C API, it doesn't appear to have made it into a released version. It looks like xerces-2.4.0 (from 2006?) includes it but newer versions don't. So upgrading to a more recent Xerces may be needed here. If Spring really depends on DocumentLS then it will need to be updated too.
When I add dependencies in Dependency Management section of pom.xml, sometimes m2e shows them in gray. Does anybody know what this means? I can see this happens when the dependencies are related to ones already added.
Is it just that they are modules of an already added multi-module pom, and is this an indication that adding them isn't necessary?
I digged into the source code of the m2e plugin and found one possible match and a possible explanation:
if(scope != null && !"compile".equals(scope)) { //$NON-NLS-1$
return Display.getDefault().getSystemColor(SWT.COLOR_DARK_GRAY);
}
From DependencyTreePage
If the dependency's scope is not empty and not compile it is displayed in grey. This may be the case, if you are adding test dependencies or provided libraries (like jsp-api etc.)
I know that since Groovy 2.0 there are annotations for static compilation.
However it's ease to omit such annotation by accident and still run into troubles.
Is there any way to achieve the opposite compiler behaviour, like compile static all project files by default and compile dynamic only files chosen by purpose with some kind #CompileDynamic annotation for example?
I have found some (I believe recently introduced) feature which allows doing so with Gradle.
In build.gradle file for the project containing groovy sources we need to add following lines:
compileGroovy {
configure(groovyOptions) {
configurationScript = file("$rootDir/config/groovy/compiler-config.groovy")
}
}
or compileTestGroovy { ... for applying the same to test sources. Keep in mind that neither static compilation nor type checking works well with Spock Framework though. Spock by its nature utilizes dynamic 'groovyness' a lot.
Then on a root of the project create folder config/groovy/ and a file named compiler-config.groovy within. The content of the file is as follows:
import groovy.transform.CompileStatic
withConfig(configuration) {
ast(CompileStatic)
}
Obviously path and name of the configurationScript may vary and it's up to you. It shouldn't rather go to the same src/main/groovy though as it would be mixing totally separate concerns.
The same may be done with groovy.transform.TypeChecked or any other annotation, of course.
To reverse applied behaviour on certain classes or methods then #CompileDynamic annotation or #TypeChecked(TypeCheckingMode.SKIP) respectively may be used.
I'm not sure how to achieve the same when no Gradle is in use as build tool. I may update this answer in the future with such info though.
Not at this time, but there is an open Jira issue here you can follow to watch progress for this feature
There was also a discussion about methods for doing this on the Groovy developers list
I upgraded to groovy 2 release and now my build is broken.
It fails when importing classes: groovy.json.JsonSlurper and XmlSlurper.
I have checked http://groovy.codehaus.org/gapi/ and cannot find these classes anymore. Do they still exist in groovy 2? Or have they moved somewhere?
The groovy.jar distributed with groovy 2 has been split out to contain just the bare minimum, with all the additional modules (XML, SQL, JSON, etc.) in separate jars. However, in the embeddable directory, you'll find a jar file groovy-all-2.0.0.jar which contains groovy and all the modules together, like previous versions. The easiest way to migrate is to use this jar file.
If you're using Maven Central, you can use an artifactId of groovy-all to get everything, or groovy (plus modules) to have finer grained control over your dependencies. Here's a list of the modules available on Maven Central: http://search.maven.org/#search|ga|1|g%3A%22org.codehaus.groovy%22
Never mind. Need to include groovy-xml and groovy-json jars.
These were split from groovy's jar. See: http://www.infoq.com/articles/new-groovy-20
When I import, groovy-json-2.4.3 and groovy-xml-2.4.3 , JsonSlurper is recognized.

I faced a similar issue in Gradle build of a Java project (Gradle uses Groovy).
Gradle stopped including the local Groovy libs in classpath automatically. So, I had to include the following lines (marked with +) in my build.gradle file:
buildscript {
ext {
springbootVersion = '2.x.x'
awsVersion = '1.x.x'
...
}
+ dependencies {
+ classpath localGroovy()
+ }
repositories ...
}
Instead of using "groovy.json.jsonSlurper", use "net.sf.json.groovy.JsonSlurper".
Your script must be running.
