Problem With Maven Compiler Plugin
When attempting to build with Maven from Eclipse I am getting the following error:
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:2.5.1:compile (default-compile) on project camel-activemq: Fatal error compiling: tools.jar not found: C:\Dev\Java\jre1.8.0_51\..\lib\tools.jar -> [Help 1]
I'm confused about why the plugin is looking in the JRE for tools.jar, when this JAR exists in the JDK.
Here is the build tag in my POM:
<build>
<defaultGoal>install</defaultGoal>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>2.5.1</version>
<configuration>
<source>1.7</source>
<target>1.7</target>
</configuration>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-resources-plugin</artifactId>
<version>2.6</version>
<configuration>
<encoding>UTF-8</encoding>
</configuration>
</plugin>
<!-- allows the route to be ran via 'mvn camel:run' -->
<plugin>
<groupId>org.apache.camel</groupId>
<artifactId>camel-maven-plugin</artifactId>
<version>2.15.1.redhat-620133</version>

RE: Problem With Maven Compiler Plugin
Posted by Mi...@faa.gov.
Thanks to everyone.
I'll try with the 1.8 JDK and the Maven plug-in version I have now (1.5.1).
BTW, is 1.5.1 the latest version or is there a more recent version of the Eclipse plug-ins?
Thanks again.

RE: Problem With Maven Compiler Plugin

As Mark pointed out, m2e requires a JDK. Initially you were using a JRE and
it will then not work. Now you changed to a JDK and it works. It has
nothing to do with the Java version.

RE: Problem With Maven Compiler Plugin
Posted by Mi...@faa.gov.
I thought I'd post one last comment about this.
For a brief period I was under the impression that fixing my dependencies somehow fixed this problem. That was not the case.
It appears the root cause was that in Eclipse I configured the installed JRE for Java 1.8. Since I have several versions of the Java JDK installed I simply changed my JAVA_HOME environment variable to point to the 1.7 JDK and then changed my installed JRE in Eclipse to also point to JDK 1.7. problem solved!
I assume the Maven plug-ins for Eclipse (at least the version I'm using, 1.5.1) require Java 1.7!!!
It would be great if someone would confirm this.

Nota Bene: to detect missing dependencies i run dependency:tree and bind to initialize phase before compilation

RE: Problem With Maven Compiler Plugin
Posted by Mi...@faa.gov.
Thank you for the reply Mark.
This problem "fixed itself". Just thought I'd explain here in the event anyone else was having the same problem.
There were some dependencies I was missing in my POM. They were libraries needed by the app (I'm new to this app and it is not normally built with Maven) and I had not included them in the POM or our repo yet. But they were not related to a plugin in any way.
When I added these dependencies to the POM and tried a compile from the command line, the build worked. Then with no changes to Eclipse I submitted the compile using Run As..... Maven build and it also worked fine.
So the error message about not being able to find tools.jar, and the fact that it appeared to be looking for it in the wrong place, appears to be just a distraction from the actual problem, in this case not including all the dependencies. I'm not sure why that would result in the error message I was seeing, but at this stage, that's a moot point.

I think the eclipse maven plugin uses the JVM that eclipse is running in, so you need to specify either a specific JDK or run eclipse in a JDK VM (this is configured in eclipse.ini if I recall correctly)
(or -not recommended- specify a specific compiler in your pom/compiler
plugin)

I think the eclipse maven plugin uses the JVM that eclipse is running
in, so you need to specify either a specific JDK or run eclipse in a JDK
VM (this is configured in eclipse.ini if I recall correctly)
(or -not recommended- specify a specific compiler in your pom/compiler
plugin)
