We're sorry this build is failing! If you can't find the issue in application code,
please submit a ticket so we can help: https://help.heroku.com/

The problem is heroku currently using Java 8: Heroku Java versions
The indicator is this line:
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.8.1:compile (default-compile) on project NCKHSV: Fatal error compiling: invalid flag: --release -> [Help 1]
I've encountered this problem when building maven application with target is Java 11 but running JDK is Java 8. I can't help with heroku since I haven't used it yet

At heroku you could really use the configurations in your pom.xml below,
please look carefully. :)
please check maven-plugin mentioned in pom.xml under <project>
I have something like this below.
...
<packaging>maven-plugin</packaging>
</project>
Futher more please check this plugin you could replace the below plugin code and modify as per your need. It can be added under build->plugins->THIS_PLUGIN
<plugin>

I hope, it helps!

Why maven cannot add my dependency to jar?

I'm new to maven and one simple thing I wanted to do is pull maven repository and use it in my project.

I read lot of articles and lot of related questions on stackoverflow about this. but still maven is unable to download the repo. and build is failing.
I used mvn compile, mvn package, mvn clean install nothing worked for me.
Please help✌️

As per the documentation, you need to have all three dependencies. That issue you have posted is not directly relevant to maven. That says the compiler cannot find symbols, may be because the class is not there in the classpath. Try with all the dependencies included.
Or in this case, what you really need the dependency for jutil-table only. You can omit the other two. But your maven pom contain jutil-protobuf dependency.
<dependency>
<groupId>com.github.chrisgleissner</groupId>
<artifactId>jutil-protobuf</artifactId>
<version>1.1.11</version>
</dependency>
<dependency>
<groupId>com.github.chrisgleissner</groupId>
<artifactId>jutil-sql-log</artifactId>
<version>1.1.11</version>
</dependency>
<dependency>
<groupId>com.github.chrisgleissner</groupId>
<artifactId>jutil-table</artifactId>
<version>1.1.11</version>
</dependency>
And build the jar including the dependencies using maven assembly plugin
<plugin>

Kindly help me to fix the issue.

Assuming you have a Main.java in src/test/java
Add this in your pom.xml
<build>
<plugins>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>exec-maven-plugin</artifactId>
<version>1.6.0</version>
<configuration>

<id>run-selenium</id>
<phase>integration-test</phase>
<goals><goal>java</goal></goals>
</execution>
</executions>
</plugin>
</plugins>
</build>
and run it via :
mvn clean install or mvn exec:java

Error generating RPM package jenkins with rpm-maven-plugin

After formatting the previous builds set up a new server using Ubuntu 4.12 32bit with XFCE . I installed and configured the jenkins however when trying to generate some build the system returns the following error:

The answer from our friend Etan Reisner is correct. I installed the RPM package in Ubuntu and it worked properly. Thank you.

Maven enforcer plugin and missing dependencies

Here is a minimal project:

When running:
mvn -Dcustom=some-value validate
Validation goes OK.
When running:
mvn enforcer:enforce
or any phase from validate to process-resources
mvn validate
mvn initialize
mvn generate-sources
mvn process-sources
mvn generate-resources
mvn process-resources
I get expected fail with message:

But when I run any other (later) phase from compile up to deploy e.g.:
mvn install
I get the error about missing dependency but there is no fail caused by enforcer plugin:

It looks for me like enforcer plugin is not executed at all, or dependencies are checked first before project can be build when running compile and later phases.
But why dependencies are not checked when running up to process-resources?

Obviously you seemed to have changed the settings of the maven installation which went wrong based on the error message:
[WARNING] Some problems were encountered while building the effective settings
[WARNING] expected START_TAG or END_TAG not TEXT (position: TEXT seen ...ever maven must make a connection to a remote s
erver.\n |-->\n <s... #111:5) # C:\programs\Maven\3\bin\..\conf\settings.xml
This means first clean up the conf/settings.xml file. Best is to use the default file which came via the installation. If you need to make modification do this in the users settings.xml $HOME/.m2/settings.xml or on Windows C:/Users/UserName/.m2/settings.xml
Apart from that i don't know what you like to achieve by using something like this:
[WARNING] The POM for com.test:enforcer-dep:jar:${custom}:1.0.0 is missing, no dependency information available
Downloading: http://repo.maven.apache.org/maven2/com/test/enforcer-dep/1.0.0/enforcer-dep-1.0.0-${custom}.jar
