The project cannot be built until the build path errors are resolved.

While compiling an android project in eclipse 3.4.2, I am getting The project cannot be built until the build path errors are resolved.

I got a temporary solution from the blog http://www.scottdstrader.com/blog/ether_archives/000921.html

The resolution was to force a resave of the selected projects (and their .classpath files):

  1. Open the project properties
  2. Select Java Build Path > Libraries
  3. Add a new, arbitrary library (to be deleted later) > OK
  4. Wait for the workspace to refresh (or force a refresh of the project)
  5. The error(s) will go away
  6. Remove the dummy library

The only other references I could find were to make minor alterations of contents of the .classpath file.

Is there any permanent fix for this issue?

I ran into this annoying issue with the Play framework. It would be nice if there was some way of knowing what build errors Eclipse is unhappy about, but it's not going to tell you. With one project, I was able to close the project, rebuild the Eclipse configuration with sbt eclipse, and reopen. With an almost identical project, that didn't work. But deleting the project, rebuilding the Eclipse configuration with sbt eclipse, and importing, did the trick.

If you think you've done everything correctly but Eclipse still complains about the jars, refresh the folder where the jars are and make sure eclipse knows they've been added to the project. Specifying the file path alone is (apparently) not enough

I've faced this issue a couple of times and following the below steps has resolved both the times. 1. Navigate to C:\Users\ 2. locate the ".m2" folder and delete it.

  1. Now navigate to the particular project in eclipse and Right-click on the project > Maven > Update Project

wait until the project is updated and in my case following the above steps resolved both the times.

I was getting an additional warning

The compiler compliance specified is 1.6 but a JRE 1.8 is used

Resolving this warning make the error also go away. The steps are as follows:

I right-clicked on it, then clicked on Quick Fix. From the dialog that opened I selected Open the Compiler Compliance property page, and clicked the Finish button.

(This is same as Java Compiler section.)

In this dialog I found the Compiler compliance level drop down and changed 1.6 to 1.8, and clicked on Apply and close.

I got a message box Compiler Settings Changed which asked if I wanted to Build the project now?. I clicked on Yes.

The build path error went away.

Go to > Right CLick on your project folder > Build Path > Configure Build Path > Libraries Tab > remove project and external dependencies > apply & close

Now, Gradle refresh your project.

Added below to pom.xml file and it worked eventually: 

<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>javax.servlet-api</artifactId>
    <version>4.0.0</version>
    <scope>provided</scope>
</dependency>
