We are moving from Java 8 to 11 on a project using jaxb. As it has been removed from the JDK, it has to be included separately, which I have done via gradle config:
compile("javax.xml.bind:jaxb-api:2.2.11")
compile("com.sun.xml.bind:jaxb-core:2.2.11")
compile("com.sun.xml.bind:jaxb-impl:2.2.11")
I am able to run the project, however compileJava gradle job throws errors:
Errors occurred while build effective model from C:\Users\.\.gradle\caches\modules-2\files-2.1\com.sun.xml.bind\jaxb-core\2.2.11\db0f76866c6b1e50084e03ee8cf9ce6b19becdb3\jaxb-core-2.2.11.pom:
'dependencyManagement.dependencies.dependency.systemPath' for com.sun:tools:jar must specify an absolute path but is ${tools.jar} in com.sun.xml.bind:jaxb-core:2.2.11

'dependencyManagement.dependencies.dependency.systemPath' for com.sun:tools:jar must specify an absolute path but is ${tools.jar} in com.sun.xml.bind:jaxb-impl:2.2.11
The job finishes and there is a jar created, however when run on production server it stops with this error:
java.lang.NoClassDefFoundError: javax/xml/bind/Unmarshaller$Listener
I'm using Spring Boot v1.5.6 and gradle 4.8.1
The solution is to use a newer version of the jaxb libraries. 2.3.0 is no longer using tools.jar.

I have created a Spring Starter data jpa project and its connecting with mysql. through STS its running fine.
i wanted to deploy it individually so i clean install the application using maven and used java jar <jarfile.jar> in command prompt.
I followed the video of java brains.
Below is the error which get
JAXB is not found.
It seems that you set the scope of the JAXB dependency to provided or built the project for an old Java Version (like Java 8) that comes with JAXB and run it with a newer Java version (like Java 10) that does not come with JAXB.
You can fix this by adding the JAXB dependency to the classpath when running the JAR or by adding the dependency to your project manually(or set the scope to compile)
every pioneers,
I want to try to build Spring Roo 2.0.0.M2(http://projects.spring.io/spring-roo/) with its saying of STS 3.7.0 and JDK 1.7.0_45, and I couldn't find the solution even according the post on other sites or on " Builds failing after upgrading to Java7, Missing Tools.jar and bad class versions " .
The error messages on auto generated POM.xml are:
??????????????????????????????????????
You need to run build with JDK or have tools.jar on the classpath.If this occures during eclipse build make sure you
run eclipse under JDK as well (com.mysema.maven:apt-maven-plugin:1.1.3:process:default:generate-sources)
org.apache.maven.plugin.MojoExecutionException: You need to run build with JDK or have tools.jar on the
classpath.If this occures during eclipse build make sure you run eclipse under JDK as well at
com.mysema.maven.apt.AbstractProcessorMojo.execute(AbstractProcessorMojo.java:362) at
....
?????????????????????????????????????
Even I have tried: add JDK1.7.0_45 path but not JRE path in STS project, and even I added tools.jar directly in project build-paths, and even I use "mvn generate source" and add the generate jar into source path. The error about apt-maven-plugin:1.1.3 is still there.
Is there any person who can help? I will try to use old apt-maven-plugin latter.
I'm running Spark's example called JavaPageRank, but it's a copy that I compiled separately using maven in a new jar. I keep getting this error:
ERROR SparkUncaughtExceptionHandler: Uncaught exception in thread Thread[Executor task launch worker-0,5,main]
java.lang.NoClassDefFoundError: com/google/common/collect/Iterables
Despite the fact that guava is listed as one of Spark's dependencies. I'm running compiled Spark 1.6 that I downloaded pre-compiled from the apache website.
Thanks!
The error means that the jar containing com.google.common.collect.Iterables class is not in the classpath. So your application is not able to find the required class in runtime.
If you are using maven/gradle , try to clean, build and refresh the project. Then check your classes folder and make sure the guava jar is in the lib folder.
Hope this will help.
Good luck!
Background:
I am developing Maven multi module project.
One of the module is common module needed by other all modules.
This module contain CommonClassA.java.
common module is properly compiled.
It is installed into maven local repository properly.
One of the class(Billtype.java) in other module (EmployeeBilling) refers this class(CommonClassA.java).
Maven Dependency for common module is properly specified in pom.xml of EmployeeBilling module.
Problem:
While compiling EmployeeBilling module it throws
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:2.3.2:compile (default-compile) on project EmployeeBilling: Compilation failure
[ERROR] \MyWorkspace\Biz\EmployeeBilling\src\main\java\com\employee\Billtype.java:[79,19] error: cannot access CommonClassA
[ERROR] -> [Help 1]**
Supporting details:
dependency defined in EmployeeBilling> pom.xml:
Other classes from common module seems accessible as no error observed
There are no other errors like Class not found/file not found.
The class CommonCLassA implements Serializable
Same error occurs from Eclipse as well as commond line
I am using M2E plugin
Tools:
jdk1.7.0_02
OS: Windows 7
Eclipse JUNO and apache-maven-3.1.0
Thanks in advance!
If project builds properly using eclipse compiler then it should work with Maven.
Few things to check if its not working with maven:
Manually check in repository that jar is installed properly and it contains your class file.
Try to build project using locally installed Maven instead of maven in eclipse.
Set -DskipTest=true while installing your jar, as it can cause issues at times.
If these steps don't work then show us your pom.
With no more information it's hard to find the cause. But I also had this problems now and then, and there are some things which could go wrong:
Are you using the right JAVA version (everywhere) ?
... and the right java PROVIDER? (Oracle, IBM, OpenJDK) In my case it's often this issue, I'm sometimes bound to IBM JDK, although I try to use Oracle where I can and this sometimes breaks my build.
Is the right maven dependency VERSION used? If you depend on it multiple times, and all in the same (lower than root) dept of dependencies, Maven will just "choose" a version. It could be that thát version is incompatible with your code of thát particular dependency
Skipping tests sometimes WORKS! It has something to do with maven phases and getting stuff ready for using it elsewhere.
Good luck :)
I had the same problem. Even the jar dependency has the required class files. Finally I deleted the local maven repo and restarted the build. Now it worked without any issue.
It looks like you are using an old version of maven-compiler-plugin (v2.3.2).
I suggest you upgrade it to 3.x. it won't magically fix your issue but it will definitely give you better / more detailed error message.
I created a dynamic web project in eclipse for a web service with axis2. I then converted it into Maven project, I'm able to compile and generate war file in eclipse, but when i deploy it on server and try to build it with Hudson-3.0.0 it gives me following error:
mojoFailed org.apache.maven.plugins:maven-compiler-plugin:2.3.2(default-compile)
org.apache.maven.lifecycle.LifecycleExecutionException: Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:2.3.2:compile (default-compile) on project WebServices: Compilation failure
Unable to locate the Javac Compiler in:
C:\Program Files (x86)\Java\jre6..\lib\tools.jar
Please ensure you are using JDK 1.4 or above and
not a JRE (the com.sun.tools.javac.Main class is required).
Please Let me know what's wrong with it!
I have exactly the same problem, ever since I upgraded Hudson from 2.2.1 to 3.0.1.
Both JAVA_HOME environment variable and JDK in hudson configuration point to JDK and not to JRE.
If I run mvn compile in the workspace directory of the job, everything works well.
Looks like the hudson cannot find java_home.
In hudson settings java.home property is set correctly ?
Does any other java projects builds successfully ?
Did you do what the exception said yet?
Please ensure you are using JDK 1.4 or above and
not a JRE (the com.sun.tools.javac.Main class is required).
Sounds like you don't have Java installed. So install it.
