Seen Errors and solutions

The error occurs in maven config files named “pom.xml”.

Plugin execution not covered by lifecycle configuration: org.eclipse.tycho:tycho-packaging-plugin:0.14.1:validate-version (execution: default-validate-version, phase: validate)

Solution:

1. Inside of the pom.xml click on the red Error message.
   Select discover new m2e Connectors
   
2. Install all connectors

Solution:

1. Edit the “Run Configuration > Plugins Tab” to either “Launch all workspace and available plugins”
   
2. OR push “Run Configuration > Plugins Tab” the “Add Required Plugins” Button to import needed plugins

1. Additionally you should activate in “Run Configuration > Plugins Tab” the “validate Plugins automaticyll prior to launching”, so that dependency problems are identified before launching the pluign

Eclipse doesn't find any library in a new Eclipse RCP plugin, and complains:

cannot be resolved to a type
cannot be resolved to a type
cannot be resolved to a type
cannot be resolved to a type
cannot be resolved to a type

Solution: The libraries from the Target Platform are redirected to the new Plugin by Extensions org.eclipse.core.runtime and org.eclipse.ui

1. go to the plugin.xml > Dependencies-Tab and add the org.eclipse.core.runtime Extension
2. go to the plugin.xml > Dependencies-Tab and add the org.eclipse.ui Extension

Eclipse can not resolve Classes from depending Eclipse RCP Plugin-Projects

cannot be resolved to a type
cannot be resolved to a type
cannot be resolved to a type
cannot be resolved to a type
cannot be resolved to a type

Solution: - go to Project Properties of Project, where the dependencies can not be resolved - add the Project with dependencies to “Java Build Path” > Projects-Tab

Maven's Tycho plugin wont find the .ico file and won't replace launcher's icon. This happens because it handles the ico path, as if it would start with ${project.build.directory}/products/${product-id}

Error - 7 icon(s) not replaced in...

Solution:

1. change your path to be relative to the ${project.build.directory}/products/${product-id}, e.g.

   /../../../../de.ivu.fare.rcp.plugin/images/icons/ivu_icon_multires.ico

2. don't forget to start the path with a slash

An error has occurred. See the log file

Solution:

1. the wrong Application is selected in the product definition, it should be “org.Eclipse.rcp.core.bundle.product”
2. there are dependencies missing. Launch the applictation with a custom launch configuration, where all the required plugins will be imported.

Maven m2e and Eclipse Workspace are out of sync.
There are "out of sync" icons near the Bunlde names in Dependencies Tab.

Solution: 1. turn off auto build (sometimes need to turn off auto refresh as well) 2. clean all (NOTE: need to opt out “start rebuild automatically” in clean dialog as well!) 3. mvn clean install (sometimes it works out without this step) 4. refresh Maven projects (only if step #3 was done) 5. exit eclipse 6. start eclipse 7. refresh all projects 8. turn on auto build

as described here: https://issues.sonatype.org/browse/TYCHO-481?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

The Eclipse executable launcher was unable to locate its companion shared library.

Reason: This occures, because Eclipse's eclipse_xxxx.dll e.g. WORKINDIR\rcp\de.ivu.fare.rcp\de.ivu.fare.rcp.core\de.ivu.fare.rcp.product\target\products\de.ivu.fare.rcp.product\win32\win32\x86_64\fare\plugins\org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.200.v20120522-1813\eclipse_1503.dll can not be reached.

Solution: 1. It may occur, because the path to the lib is too long: copy the exported project to some other place 2. It may occur, becuase you do not have the rights to use eclipse_xxxx.dll - adopt the rights.

package in Eclipse is not accessable.

Solution: Try adding accessable Rules to the .classpath file.

<?xml version="1.0" encoding="UTF-8"?>
<classpath>
	<classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER/org.eclipse.jdt.internal.debug.ui.launcher.StandardVMType/JavaSE-1.7">
		<accessrules>
			<accessrule kind="accessible" pattern="*"/>
		</accessrules>
	</classpathentry>
	<classpathentry kind="con" path="org.eclipse.pde.core.requiredPlugins">
		<accessrules>
			<accessrule kind="accessible" pattern="**"/>
		</accessrules>
	</classpathentry>
	<classpathentry kind="src" path="src/main/java"/>
	<classpathentry kind="output" path="target/classes"/>
</classpath>

Abhangigkeiten, 
 - zu den Common Bibliotheken
 - zur LAUFZEIT
 - beim Starten aus Eclipse 
werde nicht aufgelost!

Solution: Mit Maven, alle bibliotheken beginnend mit root bauen. Eventuell die Serverbibliotheken deployen.

POM says: Missing artifact com.sun:tools:jar:1.6

Solution: Add the following dependency:

 <dependency>
   <groupId>com.sun</groupId>
   <artifactId>tools</artifactId>
   <version>1.6</version>
   <scope>system</scope>
   <systemPath>C:\Program Files\Java\jdk1.6.0_29\lib\tools.jar</systemPath>
 </dependency>

Solution: A defect Eclipse IDE was the reason. (One of the plugins?) Downloading a new one was the solution.

The project cannot be built until its prerequirenments X is build. Cleaning and building all projects is recommended

This happens, regulary. Probably because of circular dependencies.

Solution:

1. Close all subprojects, except of the core project.
2. Rebuild the All (open) projects. Update maven dependencies.
3. Then open the projects one by one

When implementing Android JUnit Tests.
Occurs, when the test-Project references the testED-Project as a jar.

java.lang.IllegalAccessError: Class ref in pre-verified class resolved to unexpected implementation

Solution:

Do not import the testED-Project as JAR into the test-Project. Instead:

1. Mark the testED-Project as a library.
2. Add it in ProjectProperties > Android to the lib requirenments.

TestED Project

When trying to send Http Requests in Android.
An Exception occurs: HttpHostConnectException: Connection refused Android

Solution: The Activity has no rights for the internet connection. Add to Manifest.MF

<uses-permission android:name="android.permission.INTERNET" />

When importing dependencies via lib projects or via Maven tycho. Can not start the app on device, because the same classes are imported via multiple entry points. (in app and lib apk are the same libs)

Unable to execute dex: Multiple dex files define ....

Solution: Do not use libs for dependencies and do not import dependencies via the libs folder.

When launching many plugin projects in Eclipse IDE, and Maven (mainly M2Eclipse plugin).
Sometimes Eclipse freezes, with a message “User Operation is waiting for “Building Workspace””

Solution: This may happen, because there are circular dependencies in open projects. Close as many projects as possible, and relaunch your main project. Then reopen your plugin projects one by one.

Problem: Docker failes to start with:

Solution: modify the “VirtualBox Host-Only Ethernet Adapter #2”. Enable “VirtualBox NDIS6 Bridged Networking driver” http://stackoverflow.com/questions/33725779/failed-to-open-create-the-internal-network-vagrant-on-windows10
