Scenario:
I am refactoring my application to work under java 17. Birt runtime 3.7.x is embedded in my application.
In updating to point to birt 4.9.0, I have updated my pom as follows:
<dependency>
<groupId>org.eclipse.birt</groupId>
<artifactId>birt-runtime</artifactId>
<version>4.9.0</version>
</dependency>
<!-- https://mvnrepository.com/artifact/org.eclipse.birt/birt-runtime-osgi -->
<dependency>
<groupId>org.eclipse.birt</groupId>
<artifactId>birt-runtime-osgi</artifactId>
<version>4.9.0</version>
</dependency>
When I build, I get the exception
org.eclipse.birt:birt-runtime:jar:4.9.0 was not found in https://repo1.maven.org/maven2 during a previous attempt
I have deleted and rebuilt my local .m2 directory.
When I dig around the maven repository I find the file at https://repo1.maven.org/maven2/org/eclipse/birt/birt-runtime/4.9.0/
This link (BiRT latest Runtime as one Maven Dependency for Eclipse) was resolved by manually downloading the file and pointing to a local copy. I'd prefer to avoid that, since Maven is all about avoiding that kind of scenario.
I suspect there's something in the maven path I am missing.
Thank you in advance.
I changed some existing projects from ant to maven projects.
So far so good.
All projects do have the same groupId.
Theres a project with name "ServerBase" and artifactId "server-base".
Within this project theres an abstract class "BaseService" which defines a logger via:
import org.jboss.logging.Logger;
[...]
protected Logger log = Logger.getLogger(this.getClass());
Theres another project with name "Server" and artifactId "server".
Within this project theres a class ConfigurationDAOImpl extending the BaseService-Class above.
Within ConfigurationDAOImpl the logger log is used for creating some outputs.
Within the "Server"'s POM file I have declared:
<dependency>
<groupId>com.tcom.amadeus</groupId>
<artifactId>server-base</artifactId>
<version>${project.version}</version>
</dependency>
Under BuildPath the dependency is shown very nice under MavenDependencies. I removed the old dirct/natural/ant-dependency from build path before.
If I remove it I am getting very much errors about missing classes etc.
But although I do have this dependency I am getting the followin error in eclipse (under tab markers):
The type org.apache.commons.logging.Log cannot be resolved. It is indirectly referenced from required .class files
Resource: ConfigurationDAPImpl.java
Path: /Server/src/main/...
Location: Line 24
Type: Java Problem
I tried removing the dependency and add it again but without any luck.
Both projects do refer to JAVA 1.8.
Both projects have been build with targets clean an package multiple times.
Both projects have been updated by Righclick or pressing F5.
I am using Eclipse Version: Neon.1a Release (4.6.1)
I am using apache-maven-3.3.9
I am using m2e Plugin.
Any further help would be grateful.
Thanks in advance.
There are two ways to 'solve' this:
1)
explicitly add the required dependency within the server-projects pom-file:
<dependency>
<groupId>org.jboss.logging</groupId>
<artifactId>jboss-logging</artifactId>
</dependency>
2)
change the scop of the required dependency within the server-base-projects pom file from up to now 'provide' to 'compile' or erase the scope tag at all such that the default scope is used by maven (which I guess is 'compile')
old:
<dependency>
<groupId>org.jboss.logging</groupId>
<artifactId>jboss-logging</artifactId>
<scope>provided</scope>
</dependency>
new:
<dependency>
<groupId>org.jboss.logging</groupId>
<artifactId>jboss-logging</artifactId>
<scope></scope>
</dependency>
or:
<dependency>
<groupId>org.jboss.logging</groupId>
<artifactId>jboss-logging</artifactId>
</dependency>
Some background to this from documentation:
http://maven.apache.org/guides/introduction/introduction-to-dependency-mechanism.html#Transitive_Dependencies
provided This is much like compile, but indicates you expect the JDK or a container to provide the dependency at runtime. For example,
when building a web application for the Java Enterprise Edition, you
would set the dependency on the Servlet API and related Java EE APIs
to scope provided because the web container provides those classes.
This scope is only available on the compilation and test classpath,
and is not transitive.
Thanks all.
It looks like apache logging library is not brought transitively from your server-base project. Check if in project server under MavenDependencies you see commons-logging (apache logging) jar. If not, then add this as your maven dependency in server-base project.
Repeat the above for all jars that server-base depends on.
I'm having trouble correctly importing a library into a project that I'm running. I have added the library as a dependency in the .pom, refreshed the pom, run mvn clean install, and I have set auto-import up so that the project gets updated correctly, but the project does not get added as an External Library, and I can't use it in my project. I get no errors. What am I doing wrong?
Here is the relevant part of my pom
..properties
<crowd.version>2.5.0</crowd.version>
.. end properties
<dependencyManagement>
<dependencies>
<dependency>
<groupId>com.atlassian.crowd</groupId>
<artifactId>crowd-integration-springsecurity</artifactId>
<version>${crowd.version}</version>
<scope>runtime</scope>
</dependency>
</dependencies>
</dependencyManagement>
Here is the question I was following to debug my error:
Import Maven dependencies in IntelliJ IDEA
I think you missed the point of dependency management; read more in official docs. This is a feature that you can centralize common dependency information that is then shared been different projects. All by itself, this definioition will not import the dependency.
What you probably want is just a plain dependency: drop the dependencyManagement tags, and move you dependency into the correct block in the pom.
I'm currently building apps for Apache Spark. Spark provides during runtime a lot of dependencies, which I normally need if I test/run the apps locally in the IDE (IntelliJ).
Is there any possibility to have different set of dependendencies related if I use the 'package' or the usual compile/run target in IntelliJ ?
For instance, this is a needed dependency to Hadoop
<dependency>
<groupId>org.apache.hadoop</groupId>
<artifactId>hadoop-common</artifactId>
<version>2.6.0</version>
<scope>provided</scope>
</dependency>
But the scope 'provided' does not work when I run it locally in the IDE.
If you want IntelliJ to use its own build process rather than Maven's, it's probably better to tell add a (global) library to your project dependencies in the IDE.
It definitely won't be providing these Spark JARs by default, which is what you're telling Maven here.
I am trying to build a simple Java project with Maven. In my pom-file I declare JUnit 4.8.2 as the only dependency. Still Maven insists on using JUnit version 3.8.1. How do I fix it?
The problem manifests itself in a compilation failure: "package org.junit does not exist". This is because of the import statement in my source code. The correct package name in JUnit 4.* is org.junit.* while in version 3.* it is junit.framework.*
I think I have found documentation on the root of the problem on http://maven.apache.org/plugins/maven-surefire-plugin/examples/junit.html but the advice there seems to be meant for Maven experts. I did not understand what to do.
Just to have an answer with the complete solution to help the visitors:
All you need to do is add the junit dependency to pom.xml. Don't forget the <scope>test</scope>
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.11</version>
<scope>test</scope>
</dependency>
#Dennis Roberts: You were absolutely right: My test class was located in src/main/java. Also the value of the "scope" element in the POM for JUnit was "test", although that is how it is supposed to be. The problem was that I had been sloppy when creating the test class in Eclipse, resulting in it being created in src/main/java insted of src/test/java. This became easier to see in Eclipse's Project Explorer view after running "mvn eclipse:eclipse", but your comment was what made me see it first. Thanks.
my problem was a line inside my pom.xml i had the line <sourceDirectory>${basedir}/src</sourceDirectory> removing this line made maven use regular structure folders which solves my issue
removing the scope tag in pom.xml for junit worked..
I had the same problem. All i did was - From the pom.xml file i deleted the dependency for junit 3.8 and added a new dependency for junit 4.8. Then i did maven clean and maven install. It did the trick. To verify , after maven install i went project->properties-build path->maven dependencies and saw that now the junit 3.8 jar is gone !, instead junit 4.8 jar is listed. cool!!. Now my test runs like a charm.. Hope this helps somehow..
Add this dependency to your pom.xml file:
http://mvnrepository.com/artifact/junit/junit-dep/4.8.2
<!-- https://mvnrepository.com/artifact/junit/junit-dep -->
<dependency>
<groupId>junit</groupId>
<artifactId>junit-dep</artifactId>
<version>4.8.2</version>
</dependency>
I had my files at the correct places, and just removing <scope>test</scope> from the JUnit dependency entry solved the problem (I am using JUnit 4.12). I believe that with the test scope the dependency was just being ignored during the compilation phase. Now everything is working even when I call mvn test.
My case was a simple oversight.
I put the JUnit dependency declaration inside <dependencies> under the <dependencyManagement/> node instead of <project/> in the POM file. Correct way is:
<project>
<!-- Other elements -->
<dependencies>
<!-- Other dependencies-->
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.11</version>
</dependency>
</dependencies>
<project>
I had a quite similar problem in a "test-utils" project (adding features, rules and assertions to JUnit) child of a parent project injecting dependencies.
The class depending on the org.junit.rules package was in src/main/java.
So I added a dependency on junit without test scope and it solved the problem :
pom.xml of the test-util project :
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
</dependency>
pom.xml of the parent project :
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<scope>test</scope>
</dependency>
How did you declare the version?
<version>4.8.2</version>
Be aware of the meaning from this declaration explained here (see NOTES):
When declaring a "normal" version such as 3.8.2 for Junit, internally this is represented as "allow anything, but prefer 3.8.2." This means that when a conflict is detected, Maven is allowed to use the conflict algorithms to choose the best version. If you specify [3.8.2], it means that only 3.8.2 will be used and nothing else.
To force using the version 4.8.2 try
<version>[4.8.2]</version>
As you do not have any other dependencies in your project there shouldn't be any conflicts that cause your problem. The first declaration should work for you if you are able to get this version from a repository. Do you inherit dependencies from a parent pom?
Me too had the same problem as shown below.
To resolve the issue, below lines are added to dependencies section in the app level build.gradle.
compile 'junit:junit:4.12'
androidTestCompile 'com.android.support.test:runner:0.5'
Gradle build then reported following warning.
Warning:Conflict with dependency 'com.android.support:support-annotations'.
Resolved versions for app (25.1.0) and test app (23.1.1) differ.
See http://g.co/androidstudio/app-test-app-conflict for details.
To solve this warning, following section is added to the app level build.gradle.
configurations.all {
resolutionStrategy {
force 'com.android.support:support-annotations:23.1.1'
}
}
I had a similar problem of Eclipse compiling my code just fine but Maven failed when compiling the tests every time despite the fact JUnit was in my list of dependencies and the tests were in /src/test/java/.
In my case, I had the wrong version of JUnit in my list of dependencies. I wrote JUnit4 tests (with annotations) but had JUnit 3.8.x as my dependency. Between version 3.8.x and 4 of JUnit they changed the package name from junit.framework to org.junit which is why Maven still breaks compiling using a JUnit jar.
I'm still not entirely sure why Eclipse successfully compiled. It must have its own copy of JUnit4 somewhere in the classpath. Hope this alternative solution is useful to people. I reached this solution after following Arthur's link above.
I also ran into this issue - I was trying to pull in an object from a source and it was working in the test code but not the src code. To further test, I copied a block of code from the test and dropped it into the src code, then immediately removed the JUnit lines so I just had how the test was pulling in the object. Then suddenly my code wouldn't compile.
The issue was that when I dropped the code in, Eclipse helpfully resolved all the classes so I had JUnit calls coming from my src code, which was not proper. I should have noticed the warnings at the top about unused imports, but I neglected to see them.
Once I removed the unused JUnit imports in my src file, it all worked beautifully.
Find the one solution for this error if you have code in src/main/java Utils
<dependency>
<groupId>org.assertj</groupId>
<artifactId>assertj-core</artifactId>
<version>3.9.1</version>
</dependency>
Changing the junit version fixed this for me. Seems like version 3.8.1 didn't work in my case. Issue fixed upon changing it to 4.12
I met this problem, this is how I soloved it:
Context:
SpringBoot application
Use maven to manage multiple modules
Add junit's maven dependency in root POM's dependencyManagement(rather than dependencies, their differences can be found here)
Intend to test class or folder inside one of the root module's child module
PS: If your situation does not match the context above, this solution may not solve your problem.
Steps
right click at the class or folder you want to test:
Choose More Run/Debug -> Modify Run Configuration
Change the module option to the one you want to test from root module
By default , maven looks at these folders for java and test classes respectively -
src/main/java and src/test/java
When the src is specified with the test classes under source and the scope for junit dependency in pom.xml is mentioned as test - org.unit will not be found by maven.
