I'm trying to create a project that depends on JDT core. I was using the entries in Maven central until I realized they were several years out of date. After poking around a little, I came across https://repo.eclipse.org. I found the repository I needed and added it:
<repository>
<id>eclipse</id>
<name>Eclipse Repository</name>
<url>https://repo.eclipse.org/content/groups/eclipse/</url>
</repository>
...
<dependency>
<groupId>org.eclipse.jdt</groupId>
<artifactId>org.eclipse.jdt.core</artifactId>
<version>3.10.0.v20140316-0146</version>
</dependency>
But then I started getting an error:
The type org.eclipse.core.runtime.IProgressMonitor
cannot be resolved.
It is indirectly referenced from required .class files
I managed to find the type in one of the Nexus repositories and added it:
<repository>
<id>eclipse-acceleo</id>
<name>Eclipse Repository</name>
<url>https://repo.eclipse.org/content/groups/acceleo/</url>
</repository>
...
<dependency>
<groupId>org.eclipse.equinox</groupId>
<artifactId>org.eclipse.equinox.common</artifactId>
<version>3.6.200.v20130402-1505</version>
</dependency>
Now I'm getting the error
The type org.eclipse.core.runtime.Plugin
cannot be resolved. It is
indirectly referenced from required .class files
And I cannot find the class in any of the Nexus repositories. org.eclipse.jdt.core.JavaCore
is the class referencing org.eclipse.core.runtime.Plugin
.
1. Which dependency do I need to add to include org.eclipse.core.runtime.Plugin
?
2. Is there a better way to include JDT as a dependency in Maven?
/e1
I found org.eclipse.core.runtime.Plugin
with the help of http://grepcode.com. This time, the up-to-date dependency is in Maven Central (and not in Eclipse's Nexus repo):
<dependency>
<groupId>org.eclipse.core</groupId>
<artifactId>runtime</artifactId>
<version>3.9.100-v20131218-1515</version>
</dependency>
Now when I try to run my tests, I get the following exception all over the place:
java.lang.NoClassDefFoundError: org/eclipse/core/resources/IResource
at org.eclipse.jdt.core.dom.ASTParser.<init>(ASTParser.java:177)
at org.eclipse.jdt.core.dom.ASTParser.newParser(ASTParser.java:126)
.
.
.

At this point I'm considering downloading the complete JAR and adding it as a system dependency. Is there any better way to add JDT as a Maven dependency?
