I have several projects for libraries and processes cross compiling for arm. But in one project, I have the problem with unresolved inclusions (It is compiling fine). I checked
Properties > C++ General > Paths and Symbols and
C/C++ Build > Settings > Tool Settings > Includes but my include path does not show up in the Includes (see picture, its missing my /workspace/include path)
Missing includes

I'm trying to run Jhipster sample app in my Eclipse kepler . I've downloaded the project from here and I've imported it as existing maven project but it couldn't be build . I got this exception :
The type java.util.Optional cannot be resolved. It is indirectly referenced from required .class files AccountResource.java
and many "Undefined CSS file" errors
how can I run this project in my Eclipse ?
Normally you should create your application using the yeoman generator. Install yeoman and execute yo jhipster from your command line.
a)For the java exception basically you need to remove the old version of java from your build path and add support for java 8.
You need to follow these steps
1) Right-click on project » Properties » Java Build Path
2) Select Libraries tab
3) Find the JRE System Library and remove it
4) Click Add Library... button at right side » Add the JRE System Library(Workspace default JRE)
Do not forget to set the Java jdk compiler compliance level to 1.8 (Preference -> Java -> compiler )
b) The jhipster site mentions about the configuration settings(css,javascript and html etc)for eclipse to avoid errors in eclipe. https://jhipster.github.io/configuring_ide_eclipse.html
I have imported a project (I am very new at this) and I get the following errors:
Project cannot be built until build path errors are resolved
Project FST is missing required library: 'C:program Files/Apache Group/Tomcat 4.1/common/lib/servlet.jar'
Project FST is missing required library: 'C:program Files/Apache Group/Tomcat 4.1/common/lib/struts.jar'
The project cannot be built until build path errors are resolved
Unbound classpath variable: 'TOMCAT_HOME/common/lib/jasper-runtime.jar' in project
Unbound classpath variable: 'TOMCAT_HOME' in project FST
I create a variable called TOMCAT_HOME and give it the proper directory ,but Also, we should change the project classpath to use TOMCAT_HOME rather than the absolute path.
i dont know how to do it (change the project classpath and the absolute path)
thanks !
To answer somewhat indirectly, if you configure your project build with something like Maven or Gradle, so that you can successfully build the project using the corresponding command-line tool, then it should be quite straightforward to import the project into eclipse using the Maven or Gradle eclipse plugin. I think doing so will be worth whatever trouble it causes you in the short run--just take care to make your project structure conform to the usual project structure that Maven expects or you'll be asking for trouble (it should be no problem to do so for greenfield work).
I am trying use androidVNC open source project as a Library Project in my MainProject. androidVNC has also used ZoomerWithKeys library project. I want start a activity of androidVNC library project in my MainProject by clicking on a Button.
I have done all the basic things like to define all the activity of library project in Manifest of main Project.
The problem is that i am getting following error when trying to running my MainProject -
Dex Loader] Unable to execute dex: Multiple dex files define Lcom/antlersoft/android/zoomer/R$drawable;
[2013-05-16 15:44:03 - OtherProj] Conversion to Dalvik format failed: Unable to execute dex: Multiple dex files define Lcom/antlersoft/android/zoomer/R$drawable;
Thanks in advance.
I resolve this by doing following steps:
Go to bin folder of you app and see which libraries are duplicated(in mine I had 2 supportv4****)
Hold your mouse on them and see where they compile from, keep in mind that you should keep the most important one, so if you are using appcompat and facebookSDK, you should keep that library which comes from appcompat
Go to the properties of the project of the other library (e.g facebookSDK) -> Java build path -> Libraries and delete the dependency in which the buggy lib come from(in mine, supportV4 nested in Android Private Libraries, so I delete it),
Also do it from a file manager, go to our project folder/libs and delete that buggy library if it's not cleaned by default
In that window, after deleting, choose Add Jars... and select the library of the other project(in mine, I choose SupportV4 from appcompat)
Clean you workspace, restart Eclipse
The problem should have gone, these steps work more than fine for me
1).did you added your lib project to the main project?? Make sure..
2).also add the project to your lib project by doing this process--
In the lib project-->>right click on project-->>java build path-->>on the project tab-->>add your main project.
Now build your project..hopefully it will help you.
EDITED::
3). Go to the project properties..edit this(can give some space) and then save..clean project...then build..
I tackled with this kind error in Android Studio.
In my case my main project was using two my own lib. But beside this those two libs were using the same library as external included
compile files('lib/external-lib.jar')
I solved it by doing following in my both own libs.
1)Removing old compile files('lib/external-lib.jar' ) from build.gradle and deleting old external_lib.jar from lib folder.
2)Adding library from jcenter() two my own libs
compile 'external.lib:1.9.2'
3)Rebuild.
Then rebuild and run main project
Then problem has disappeared.
I imported some JTB and JavaCC generated files into Eclipse and there is one line giving me an error - the first line (a comment) most of the class files says "The type java.lang.Object cannot be resolved. It is indirectly referenced from required .class files" How do I fix this?
Have you tried removing and adding the JRE in your project?
Select Project -> Properties
Select Java Build Path
Navigate to the Libraries Tab
Remove the JRE
Click Add Library and add the default JRE again
PS: Project -> Clean can be very useful, too.
I have a 'Utilty Project', and an 'EAR Project' that includes that 'Utility Project'. All the classes from the 'Utility Project' end up being packaged as a JAR and placed within the 'lib' directory of the exported EAR, for example:
EAR.ear
META-INF
MANIFEST.MF
lib
utility.jar (which expands to):
META-INF
MANIFEST.MF
com
acme
Foo.class
Bar.class
However, the 'Utility Project' relies on a library (freemarker.jar) that has been added to the build path using 'Properties > Java Build Path > Libraries'. All I want to do is to get freemarker.jar added to the EAR as follows:
EAR.ear
META-INF
MANIFEST.MF
lib
**freemarker.jar**
utility.jar (which expands to):
META-INF
MANIFEST.MF
com
acme
Foo.class
Bar.class
By searching around within Eclipse I've found 4 potential avenues for achieving this, none of which have worked. If someone can just cut to the chase and tell me what I should actually do, that would be great. But just in case, I'll iterate them here:
From the 'Utility Project' Properties:
If I click 'Java Build Path > Order and Export' and select 'freemarker.jar' for export, the jar does not end up in the EAR file at all.
If I click 'Java EE Module Dependencies' and select the 'freemarker.jar' library as a dependency, it says:
This JAR is a bundled library of an
EAR project and is supposed to be
packed in the EAR's library directory.
It conflicts with the manifest class
path dependency you are trying to
create. If you create this dependency,
the JAR will be packed in the root
(not library) directory of the EAR.
Are you sure you want to proceed?
From the 'EAR Project' Properties:
If I click 'Java EE Module Dependencies > Add JARs...' and navigate to the 'freemarker.jar', and make it a dependency, it gets added to the root of the EAR:
/freemarker.jar
If I do the same as above, but check the 'In Lib Dir' checkbox, it gets added into the lib folder, but contained within another lib folder:
/lib/lib/freemarker.jar
Thanks.
I've managed to solve this problem. In the Problems window I was getting the following warning:
Classpath entry /utility-project/lib/freemarker.jar will not be exported or published.
Runtime ClassNotFoundExceptions may result.
What I tried, at a whim, was to use the Ctrl-1 key combination I've been using to get quick fix solutions for my source code. It turns out this also provides quick-fix solutions for for the given errors and warnings. I chose the first of the two options:
Mark the associated raw classpath entry as a publish/export dependency.
and my problem disappeared!
Bizarrely, all this seems to have done is to cause the 'freemarker.jar' lib to be selected in the 'Java EE Module Dependencies' properties dialog, which I was doing myself anyway. This may be an Eclispe bug!
#MonoThreaded: After using the quick fix > Mark the associated raw classpath entry as published/export dependency, if you right-click on the project > properties > depolyment assembly you will notice that eclipse has added a new entry, something like source: /freemaker.jar, deploy path: ../lib. You can do that too, by selecting Add > Java Build Path Entry.
